Net neutrality promoted competition among broadband ISPs, and after it was repealed the biggest ones worked quickly to consolidate power. Now we've basically got only two major broadband ISPs in the US, assuming you don't want shitty unstable DSL anyway, and so these corporations got exactly what they wanted. No need to worry about throttling speeds for the smaller/local ISPs, because they no longer exist.
Until the de facto duopoly was in place, we didn't have data caps for home internet in my state. We do now though, courtesy of Comcrap.
