Re: [Bloat] How about a topical LWN article on demonstrating the real-world goodness of CAKE?

Consider starting from the incorrect default premise in many households:
if you want to get something done, yell at the teenagers to stop
streaming.  Make the point that many people fail to recognize that "manual
traffic management" is really a workaround for busted network devices.  It
would be cool if you had an easily reproduced manual example, such as poor
interactive response on one device while running a speed test on another
device.

To be simplistic, you might just talk about cake vs (bloated) drop tail.
To be thorough, you also need to make the case that cake is better than
other AQMs.  This feels like too much for LWN, but silence on other
solutions might trigger skeptics.

I think your main audience is the extended WRT community - the people who
you want to bake this into future products.   Think about what side issues
might matter to them (no manual config?).    Although gamers also care,
they are an easy sell.

We must not tolerate intolerance;
       however our response must be carefully measured:
            too strong would be hypocritical and risks spiraling out of
control;
            too weak risks being mistaken for tacit approval.
