You're approaching this as an emotional partisan fight, which couldn't be more disconnected from what's going on.
ISPs wanted to frame this as a free market vs gubmint takeover, but it's nothing like that. As
scott aptly described on the other thread on the subject, most of these ISPs are currently enjoying a government subsidized Natural Monopoly which they don't want to lose. There's nothing "free market" about that. As I said, government has been knee deep into regulating the internet and everything surrounding it since the very beginning.
The real "free market" solution to this would be to rid the monopoly power from these companies and let everyone compete. But neither the ISPs that are crying foul nor the government are taking that route, so it's moot.
Time will tell how this all works out, but this is strictly a battle between large business interests. The politicization of all this is how you end up with "Net Neutrality Obama version" or "Al Gore invented the internet", which is a distraction.
