You seem to be confused. No one on mastodon can stop you from speaking. They can just choose not to listen. Censorship would be stopping you from speaking. As long as you're not breaking any laws, no one is going to shut you down and prevent you from being on the network (eg, your hosting company shutting you down). All you stand to lose is a generous system administrator doing the work of staying online for you for free.
