I think the reason it's not discussed by consumer ISPs is because the big guys are using a wide range of technologies, from DSL (yes, still) to cable to fiber.

I think the reason it's not discussed by consumer ISPs is because the big guys are using a wide range of technologies, from DSL (yes, still) to cable to fiber. They don't want to talk about how their 200Mbps cable customers have significantly worse internet than their 200Mbps fiber customers. If they did that, they'd have to go deploying fiber into all the places that use other technologies.
