A lot of not-so-subtle support for 8chan leaking into this thread. Cloudfare aren't a government. They aren't a democracy. I don't know why some people seem to think they should act any differently. If you own a notice board in the real world, and someone put something horrible on it, you would take it down. This is no different.
They are utility though. Have you thought about that people support neutrality/common carrier style behavior with 8chan existing being the acceptable price to pay and not 8 chan itself?
They are comparable to a self-storage place you might keep your boat. Or an office you might rent to house your business. But they are not anything like a utility.
