Right. So if I mute you, you're not censored. If I use a platform's tool to remove something you posted, you're not censored. Your post is still available on potentially infinite other platforms and relays. For example, if I have a community forum about cars and you post about trees, I'm going to remove it from the community that I moderate. But community platforms that don't have moderation tools would still show it and as I said, it's not technically deleted so your content exists everywhere else.

If the platform itself removes or filters out your post, then I could argue it's censorship or shadow banning.
