However these are communications platforms. So is it clear that if AT&T wanted it could say I cannot talk about my silly hats only club, they could intervene to block my communications?
Or if my landlord felt I shouldn't have a specific sign (not signs in general), or even to just say words they dont agree with, they could bar that from their property?
Or if I wanted to wear a democrat colored pair of shorts to a (business owned) pool they could bar that dress code?
These are all business contexts in which I'm using the business owners property as a customer/consumer and hypothetically being barred from an action. I dont see how it's so different for communications platforms like Reddit/FB/YT
Perhaps America is far less free than I realized.
