This assumes anti-competitive authorities as monopolies but that is as far from reality as can be expressed.

Amazon Kindle doesn't own the content of the books to be able to censure them, they can't legally censor or edit books that weren't censored or edited by the writer/publisher.

Also, there are dozens of ebook stores - a vast competitive market to choose from - not to mention many libraries have ebooks and print books available and interlibrary loans are awesome to get things you want even if not available locally.
