A business deciding how its facilities are used isn't censorship. If I go to a movie theater, buy a ticket, and then start shouting at the audience about how Jews control Hollywood, they'll throw me out. If I mail a dick pic to the newspaper and demand they publish it, they will not. Are you saying these things are censorship? Certainly, they're about businesses limiting "free speech".

To use a closer analogy, Tumblr recently banned "adult content", including nudity. This affected friends of mine. Is that censorship?

Ok, so why can Patreon not decide what is and is not an acceptable use of its platform?
