The difference between food and waste is also obvious, still we bring the waste to the garbage can.

Also, nobody censors. A distributor decided not to distribute the stuff anymore.

This “well it’s not really censorship if it’s not the government” point is useless, shallow, and ultimately meaningless. Your garbage analogy (no pun intended) fails on its face because in that case the government is explicitly telling you what is trash and what is recycling; what is compost and what requires special disposal.

This idea begets that we have agreed to outsource what is and isn’t “allowed” to be said in the public space (and these are public spaces) to private corporations that absolutely do have their own agenda and objectives. Are we as a society ready to do that? Who watches the Watchmen?

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?

Sure, fine, let’s look at it that way. But then we have to accept that these businesses are responsible for everything they allow. We can hold them responsible for any copyright violations and defamation they carry since according to you they ‘decided it was acceptable use’.
