However, for essentially unmetered, cabled Internet access, in the US, it is mostly the case of only one "last mile" access ISP being available to a given household, two in many urban and suburban environments, and infrequently three. Which says to me, competition on the basis of "ATM-like class or quality of service" knobs, provided by your ISP, won't help much, unless everyone uses the same techniques?

There will be other last mile providers for a lot of people. 4G can provide acceptable bandwidth (in my case faster than FTTC), there will be 5G, Starlink is rolling out and there are others LEO offerings.

If DSL has to fight back it can offer enhanced services.

I have always thought that there might be a possibility of DSL offering service to multiple ISPs over the same path since all offerings are multipliable at the L2 they use. So you could have the FAANG group offer prioritised direct to the home in parallel with classic worst efforts service.
