It's distressing how little the tech press understands the real problem.

Of course, cable companies like Charter and ATT who have mostly DOCSIS 2 gear deployed can't admit to their plant being bloat-causing.

In fact it protects their cable business against cord cutters.

And the solution is needed in the CMTS once neighbors all start becoming heavier users, because it is a shared buffering pool with no fairness or bloat protection.

Still, routers with queue management that reduce bloat would help a lot, if "buffering" is seen frequently under load.

So why isn't anyone talking about this problem after at least a decade of knowing it, and knowing how to fix it?

I blame IETF members, individually and collectively. If ietf exists for any reason other than as a boondoggle for world travel, it's for resolving issues like this one.
