Sure, but this is a property rights issue not a issue of censorship. I don't agree with your "societal infrastructure" premise, but that doesn't change what would need to be done. What you're talking about is an anti-trust issue. You can't force a property owner to host content against their terms of service.

Censorship can be done by anyone with a platform. It's only a 1st amendment issue if it is done by the government.

I work in a helpdesk, so most of my day is dealing with the people that would be above described as the stupid people. I am not going to try to defend them, because its true, they would click on a land mine, labeled landmine, with a warning telling them that it may blow off their damn hand if they clicked on it.

However, it amazes me the amount of them that say their actions match mine in so the way they say they will never buy something that is advertized though annoyance.

Of course when they say it it sounds more like "They thinks I'll be buying this shit that they all put in my face when I am all tryin to chat? F--K THAT!"
