The current wave of censorship, banning books and podcasts, is politically driven. I understand the itch to try to route around the damage it causes, and take back control via technical means. That requires the mass of users to shift platforms, and once they do, the political will to censor will follow them there, digging as deep into the infrastructure as is required to re-assert control.
Going down this path will eventually result in a war against general purpose computing itself. Let's not go there.
A political problem (the rich want to keep getting richer, so they promote efforts to censor podcasts, books, and the questioning of authority), is best met with a political answer. Reject the false choice the 2 parties, and 2 thought bubbles give you. Think outside their boxes. What policies do you want from your government? Ignore the wedge issues, push for the changes you want, and think are reasonably agreeable with most of the rest of us.
