Cambium screwed that up. They literally broke the law by providing instructions to bypass encryption (The provided it to me, their claims to the contrary are lies.), which is a DMCA violation and isn't covered in fair use because cambium didn't own the devices. They also used a contract encumbered beta firmware they weren't allowed to touch per various trade secret laws and that was provided by a wisp that was also sued for confidentiality breach. Ubiquiti basically had no choice but to sue them. Plenty of rules on the book about having to defend your copyrights, trademarks, and contracts else they are void. Cambium was who screwed up here, big time. They could have and should have made the elevated firmware OR offered it as an openwrt module and published supported chipsets. The community would have figured the rest out from tftp recovery installs or their own beta firmwares which they had fair use on and Ubiquiti would have no obligation to defend anything and no standing. I don't like how Ubiquiti handled it, but legally speaking they had little choice but to do something. Cambium on the other hand royally screwed up. As evidenced by Ubiquiti losing nothing, changing nothing except tightening up even more and even disengaging in the community and Cambium lost a product line entirely with immediate halt of sales and barred from distribution or even support and even stroked UI a check... That's an exceptionally one sided settlement. open source licenses of course stomped on pretty hard by both parties. IMO, there is no practical way to target the CPE with updated firmwares to provide AQM there. Too many vendors, no compliance on GPL for firmware though they are all using openwrt underneath except Mikrotik and cambiums 450 line. Operators have fair use on our products so as long as LibreQOS never provides instructions to bypass or break encryption then that's not an issue, just the practicalities of actually doing this. The type of wISP that is really interested in AQM in any way is also likely the ones quickly leaving the old hardware behind. I have a dominantly ubiquiti network and <5% of them are old enough that they came with an unencrypted bootloader or anyone at openwrt has figured out how to work around, and even if I did I wouldnt get airmax anymore, I'd have to go to straight 802.11ac which is substantially inferior. In other words, a LOT of work for little to no gain practically speaking. Slight divergence here... If you search the mikrotik forums, I've asked for an outdoor device with an ARM CPU that has 12-60V PoE IN and matching PoE out to function as a bump in the wire. Could be used as a bridge device injecting option 82 and doing a bridge shaper, or could act as a router, or even just to capture packets etc. You could use a device like this to sit between an access point and it's POP switch or router, or whatever novel network design you can think of... Then push customer upload shaping off to that device as well. Go bump that if you like the idea. They have the wAP AC that is very close, but it doesn't pass through PoE. So I think that the only practical option is to either target just the edge, or edge + tower sites, or find a device that can act as the dmarc for customers like mikrotik's GPEN21 which runs their SWOS and I don't know if you could get openwrt on there.

"sale" involved, us (IMHO) doing something elevate-like for free = on
*old* ubnt or cambium hardware leveraging the openwrt builds, is
untouchable, legally, and of huge benefit (and savings on capex) to
ISPs given how much better modern software works on this old hardware,
in particular. fq_codel "just works" on the wifi and ethernet
interfaces, there's BQL, and IPv6, supported. The ubnt M5s were my
first target for the fq_codel work, the first to get fq_codel for
wifi, and the backbone of my network at lupin. Vastly better than the
original firmware. There is limited flash so the m5s were obsoleted by
openwrt 22.03, but there is another build for them within those memory
requirements elsewhere, and 19.x was more than good enough. So for the
old hardware, openwrt is not presently affected by their
noncompliance.

But IMHO moving forward! on newer gear they are producing, their lack
of gpl compliance is becoming a real problem, and lag on things like
ipv6, etc, also.

Ideally we find ways of integrating with their current products (or
they end up using our stuff!) and otherwise, we should steer clear of
the lawyers in our pursuit of a better internet for everyone, running
on everything.

We're all in this bloat together.

PS Also to this day, I love the ubnt Picostations. Incredible range
compared to what you can get today, and they last forever....
