The question I struggle with is how to get ISPs to care and put pressure on CPE manufacturers to fix bufferbloat in their products.

I performed some tests on my Zyxel router, and the WiFi link was terribly bloated when there were a few walls between my laptop and the router. The latency almost reached 10 seconds under load! My ISPs response was that some buffering is normal (some = 10 seconds??) and that artificially saturating the link doesn't represent a normal use case. Keep in mind that this was at the edge of the WiFi coverage with a maximum data rate of 15 Mbps, a speed that's relatively easy to reach. I followed up with an email about how there are solutions to this issue and that they should put pressure on Zyxel to implement them, but alas, there has been no response and it has probably fallen on deaf ears.

As noted above, it not just the CPE devices, it’s the congestion on the backhauls that causes issues, and it’s everything from DSL (slammed DSLAMs are endemic) to cable systems with oversubscribed local loops and congested CMTS backhaul. Hell, even fiber to the home ISPs manage to have variable capacity (and bloat) in the evenings.
