It's not if you consider being an isp like a utility. If the power company had a way to shut your power off anytime you tried to access a web site.

I also disagree with what the other companies did in the first place is censoring. They're removing rule breakers. You can still share your political views, just don't organize and call for the government to be other thrown because you believe everything you read online. You wouldn't freak out because a child porn distribution platform was turned off and claim it's censored.
