We agree then, this is "censorship", but has nothing to do with "freedom of speech" as codified in US law.
> but has nothing to do with "freedom of speech"
It absolutely has something to do with the general concept of freedom of speech, actually.
Freedom of speech is a concept, not just a law.
It would have a pretty small effect on other people's ability to engage in speech. But it is an effect none the less.
If you owned a huge amount of property, though, then this would be a larger amount of censorship.
