Edit: You know what, fuck it. I don't think I can say anything here that hasn't been said a thousand times already.
This topic is already highly partisan, of course, so it's all the more important not to make it more so. This is very much a collective responsibility.
I don't have a party, and net neutrality is one of the few political issues Hacker News has officially done something for, including quite recently. I don't fault you for not knowing that, because most people see only a tiny slice of what passes through here and no one sees all of it. But the dynamic of jumping to a view of someone as your enemy is a thing we all need to work on.
That being said, I think it's pretty clear that more harmful policies proposed in recent times have come predominantly from a single source, and I think it's more important to work in opposition to that harmfulness than to find a group that perfectly represents you. Especially with a first past the post electoral system in which fractiousness dilutes the value of your vote.
Saying Pai is Obama's fault is disingenuous, because he had to appointment a Republican, and any Republican chair would implement Republican policy.
That's pretty rich for being the "party of personal responsibility".
Ajit Pai has the confidence of Republican leadership and was appointed by Obama at McConnell's behest, again because of requirement. I'm sure if Obama could have appointed a political ally he would have.
Ajit Pai certainly is responsible for this, but he is acting on behalf of the GOP and has their full backing. I think it's fair to hold them accountable for that.
Politics are more nuanced than red or blue.
