I largely believe the problem isn't ISPs anymore, it's content-providers. Content is getting increasingly centralized by so-called "content providers" instead of ISPs. People's experience of online censorship is probably a couple orders of magnitude greater when it comes to the increasingly restrictive rules of Facebook/Google/Twitter/Pinterest/YouTube/etc.* (all in the name of being advertiser friendly). My one and only experience with ISPs censoring content was a long time ago when my torrents were throttled. I've never had the ISPs (short of government intervention) block a tweet, a status update, a video, or an online service since then. So when people's experience of online censorship is with content providers, not ISPs, how can we expect to sell the public on Net Neutrality when it doesn't touch the largest experiential part of online censorship? There's an elephant in the room and we're screaming about the mouse in the corner.
