Already users are like "how can i fix this!".
I've just replied to one who has lower speeds on the surfboard SB6141 which is a modem designed for crazy cable speeds. He has an "F" and his downstream bloat is terrible, and upstream not much better.
I imagine a LOT of people on slower plans have a "recommended" modem like this one.
However most of them will hear that the problems from bloat only happen when you reach maximum upload or download speed and will think, well, I can live with that, I never run my connection to capacity and I don't upload to offsite backups..
