Some action against Comcast throttling/blocking BitTorrent (in 2007-2009) ultimately resulted in action by the FCC in 2010, made rather toothless in 2014 with the provisions against blocking and throttling struck down.
So between 2010-2014 and 2015-2017 we have ~6 years of regulation, with the ISPs fighting it all the way (surprise surprise).
Just to clarify: I'm in agreement that we need net neutrality. I've just been around the block enough times to know that the FCC's latest action just isn't the end of the world.
