Any quote on that?

I’m not sure this is a fair statement. Comcast is a major (if not “the” player) in CableLabs, and they made it clear that for Docsis 3.1, aqm was one of the important target. This might not have happened without all the noise around bloat that Jim and Dave made for years. (now peering and transit disputes are another ball game)

While cable operators started pretty much with a blank slate in the early days of Docsis, they now have to deal with legacy and a huge tail of old devices. So in this respect, yes they are now a bit like the DSL incumbents, introduction of new technologies is over a 3-4 years timeframe at least.

You might be surprised at how much they care for gamers, these are often their most vocal users. And those who will call to get things fixed. Support calls and truck rolls are expensive and touch the bottom line, where it hurts…
