Very unpopular opinion. The internet should be free for everyone and no provider should have the ability to cut off services. The problem is not the platform but the people, hate the player not the game.
How do you filter spam if you can't moderate at all? HN only exists as a service because it's quite carefully moderated.
Communications Decency Act of 1996, Section 230 allowed platforms to not be held liable for user generated content. But it did not allow publishers to have the same freedom.
Notice the very important distinction between "platforms" vs "publishers".
A publisher like a newspaper can be sued for content they put out. A platform cannot be sued for the same. When companies like CloudFlare start banning people for political reasons, they are stepping into the "publishers" market and should be stripped off of the protections from the CDA Section 230. We should be allowed to sue them for content they carry.
Right now, they are enjoying the benefits of both - platform and publisher.
