The problem is Congress and the FCC bear just as much culpability for the anti-competitive telecom markets as the state governments.

It's naive to think that a group that created these monopolies have any interest in the sort of deregulation that would actually encourage competition, and in particular would allow the success of new telecoms/ISPs.

What's naive is describing Congress and the FCC as monoliths with singular, easily defined interests.

However, even if there was more competition, ISPs would still potentially be able to demand money from less prominent services that consumers are unlikely to switch ISPs to use, and exempt their own services from data caps.
