"
if they don't want a legion of pissed off Netflix customers who feel trapped by their ISP"
This is supremely dangerous to Verizon.
Taking the US political area I know best, gun owning households are a majority in the US, but of course those who vote, vote first and foremost on this issue, let alone be politically active are the usual successively smaller fractions of that huge number.
And starting in the mid-80s we've been able to move mountains (details on request). The last thing the big incumbent landline last mile providers want is a large percentage of the population getting pissed off and doing the above, voting when they might not otherwise bother, especially in state and local elections, voting on this issue, and becoming politically active on it.
I think the incumbents' behavior is so outrageous that this is eventually inevitable, Netflix's PR attack, in part enabled by their being so big, has the potential to substantially move that day of reckoning forward, and is therefore probably the biggest thing to happen in the net neutrality fight since AT&T's Edward Whitacre opened his foolish mouth and really got the issue started 8 years ago.
