Some third party forum/social media site failing to host your writing for eternity is not even slightly the same thing as censorship.

If you've written a bunch of stuff that you think is valuable and you want to make sure it's available forever then you should make a blog and host it yourself. (Which you have sort of done by writing a book, but you didn't need to go that far if all you cared about was longevity)
