Only the latter matters, as ordinary users don’t care what happened to the packets in transit. Yet the relevant academic literature fixates on the local operation of the mechanisms (including Traffic Management), not their global aggregate effect.

	[SM] The EU laid out pretty clear why they mandated the NN regulations in eu regulation 2015/2120:

[...]
(8)
When providing internet access services, providers of those services should treat all traffic equally, without discrimination, restriction or interference, independently of its sender or receiver, content, application or service, or terminal equipment. According to general principles of Union law and settled case-law, comparable situations should not be treated differently and different situations should not be treated in the same way unless such treatment is objectively justified.
(9)
The objective of reasonable traffic management is to contribute to an efficient use of network resources and to an optimisation of overall transmission quality responding to the objectively different technical quality of service requirements of specific categories of traffic, and thus of the content, applications and services transmitted. Reasonable traffic management measures applied by providers of internet access services should be transparent, non-discriminatory and proportionate, and should not be based on commercial considerations. The requirement for traffic management measures to be non-discriminatory does not preclude providers of internet access services from implementing, in order to optimise the overall transmission quality, traffic management measures which differentiate between objectively different categories of traffic. Any such differentiation should, in order to optimise overall quality and user experience, be permitted only on the basis of objectively different technical quality of service requirements (for example, in terms of latency, jitter, packet loss, and bandwidth) of the specific categories of traffic, and not on the basis of commercial considerations. Such differentiating measures should be proportionate in relation to the purpose of overall quality optimisation and should treat equivalent traffic equally. Such measures should not be maintained for longer than necessary.
(10)
Reasonable traffic management does not require techniques which monitor the specific content of data traffic transmitted via the internet access service.
(11)
Any traffic management practices which go beyond such reasonable traffic management measures, by blocking, slowing down, altering, restricting, interfering with, degrading or discriminating between specific content, applications or services, or specific categories of content, applications or services, should be prohibited, subject to the justified and defined exceptions laid down in this Regulation. Those exceptions should be subject to strict interpretation and to proportionality requirements. Specific content, applications and services, as well as specific categories thereof, should be protected because of the negative impact on end-user choice and innovation of blocking, or of other restrictive measures not falling within the justified exceptions. Rules against altering content, applications or services refer to a modification of the content of the communication, but do not ban non-discriminatory data compression techniques which reduce the size of a data file without any modification of the content. Such compression enables a more efficient use of scarce resources and serves the end-users’ interests by reducing data volumes, increasing speed and enhancing the experience of using the content, applications or services concerned.
(12)
Traffic management measures that go beyond such reasonable traffic management measures may only be applied as necessary and for as long as necessary to comply with the three justified exceptions laid down in this Regulation.

There really is little IMHO that can be brought against these, all pretty fair and reasonable. What it does is accept that internet access is essential infrastructure and that hence access needs to be as well regulated as access to water, electricity, gas, streets, ... . Yes this has some consequences of what ISPs can and can not do. But this is normal "cost of business". I for one am quite happy about this regulation existing as locally it did away with some (not all) shenanigans of some ISPs that were clearly not operating in the interest of their paying eye-balls.

There is a whole cottage industry of consultants that decry the EU's decision and try to lobby against it, but honestly reading these mostly makes me think harsher regulation might be required (on consultans about how much they are allowed to massage the facts ;) ).

P.S.: Of course if we look close enough we surely can find corner-cases where either the EU regulations or the translation into national law result in less desirable outcomes, but "nothing is perfect" and all in all the regulations seem to be "good enough". With the caveat that explicitly excluding ISP interconnect from the regulations BEREC essentially pointed the way for ISPs wanting to monetize their eye-balls twice to do so via interconnects, but that only works for the 800 pound gorillas and generally is not a game smaller ISPs can play. I do understand why BEREC wants to stay out of the interconnection issue, as this is rather complicated and the market seems to generally work okay-ish (that is not badly enough to make intervention a hot-button issue for voters and hence politicians).

We typically pay 900-1400 for a gig of service.  This isn't abundance and it's widespread and it leaves only major providers that can afford/amortize out 100G transits etc.
> My answer to this is one that Dave and I have bounced back and forth is the idea of micro IXs in every municipality and having that somehow tied into access to the ROW in counties etc.  Not fully hashed out, but the fiber is in the ground, it could be sold, but the carriers are not well incentivised to sell it.  It takes the better part of a year to get a DIA within 100ft of a Lumen hut sometimes...  Heck, it could even be a government program to get an μIX with x feet of every school, city hall, and library.  I don't care how it's done but this would get abundance NEAR end users and open up essentially every town to competition.
>

They have enjoyed virtual monopolies with cable owning population centers and DSL owning the outskirts and there is no product darwinism here where customer satisfaction is a pressure.  That may not be the future but it definitely is the past.  These companies may have to shift into customer satisfaction as a major part instead of a minor part of their corporate culture to fend off fttx and ultra-modern wisps.

> Only fttx and ultra-modern wireless tech really threatens these incumbents.  Typical wisps aren't putting a dent in these guys, just scraping the paint off their bumper.  We're pulling customers at the scale of 'dozens' for example.  Spectrum's management doesn't know we exist we're such a small threat to them.   
> 
> But to further the point here, these fttx and ultra-modern wisps can only exist in places where there is adequate carrier services to start with.  In areas where they spend the money and do the build but there aren't good carrier services, those fiber services suck and the wISPs start to claw back even with inferior technology.  We've pulled quite a few customers off fttx deployments because of this sort of situation.

But a second large portion was a money grab from ISPs thinking that they could hold up large paid websites (netflix for example) for additional fees by threatening to make their service less useful to their users (viewing their users as an asset to be marketed to the websites rather than customers to be satisfied by providing them access to the websites)

It's not usually necessary, for example, to specifically enhance service for latency-sensitive traffic, if FQ does a sufficiently good job.  An increased link rate *does* enhance service quality for both latency-sensitive and capacity-seeking traffic, provided FQ is in use.

This also caused subscribers using swarm traffic to impair the service of subscribers who had nothing to do with it.

ISPs' initial response was to outright block swarm traffic where they could identify it, which was then softened to merely throttling it heavily, before NN regulations intervened.  Usage quotas also showed up around this time, and were probably related to this problem.
> >

Swarm applications nowadays tend to employ altruistic congestion control which deliberately compensates for the large number of flows, and/or mark them with one or more of the Least Effort class DSCPs.  Hence, swarm applications are no longer as damaging to service quality as they used to be.  Usage quotas, however, still remain in use as a profit centre, to the point where an "unlimited" service is a rare and precious specimen in many jurisdictions.

Some ISPs began to actively degrade Netflix traffic, in particular by refusing to provision adequate peering capacity at the nodes through which Netflix traffic predominated, or by zero-rating (for the purpose of usage quotas) traffic from their own media empire while refusing to do the same for Netflix traffic.
> >

NN regulations forced ISPs to carry Netflix traffic with reasonable levels of service, even though they didn't want to for purely selfish and greedy commercial reasons.  NN succeeded in curbing an anti-competitive and consumer-hostile practice, which I am perfectly sure would resume just as soon as NN regulations were repealed.
> >

The ISPs behind L4S actively do not want a technology that works end-to-end over the general Internet.  They want something that can provide a domination service within their own walled gardens.  That's why L4S is a NN hazard, and why they actively resisted all attempts to displace it with SCE.

It is actively difficult for Internet users to move to a truly different service, especially one based on a different link technology.  When attempts are made to increase competition, for example by deploying a publicly-funded network, the incumbents actively sabotage those attempts by any means they can.  Monopolies are inherently customer-hostile, and arguments based on market forces fail in their presence.
