If you look at one of my other responses in this thread, you'll see I am largely in favor of ISPs being able to experiment with alternative models of billing for Internet usage. Bear in mind, the whole "you'll suddenly have to pay extra to see this website" nonsense is just that... nonsense.
Also, bear in mind, ISPs are a tiny threat compared to Google. None of the ISPs we're talking about have a scope outscaling the United States, but Google is a global threat that has the influence and power to bully individual countries into compliance with what they want. Suffice to say, the ISPs are not the giant entity here, relatively speaking.
ISPs can and should be fought by the FTC when they engage in unfair business practices or collusion. Ajit Pai's plan includes granting the FTC additional authority to do just that.
Also, we've already started to see wireless home Internet plans in the 4G space, and that's likely to continue to grow when 5G launches. A lot of households are mobile only at this point, which presents a very different avenue of competition. I have and will always have a wired landline, but the wireless competition with wireline providers will likely help keep things moving on a competition front.
