I would probably not be happy at all, but I guess free speech is free speech
actually there is no such thing on private property, while the internet is public and not bound by any specific international laws, just rulings of ICANN,
so anyone can put a server up and they have `free speech`, which is infact much freer that free speech guaranteed by the US constituion, but the content posted is bound by the rules of the country the poster is in.
However other peoples websites are private property and free speech does not exist and thus they can do anything they want. It's not as if in real life you want walk onto someone elses property uninvited and spray paint propaganda all over their house and expect to get away with it.
