someone made a censored draft

I don't think we can quite say that. Speeches usually have a time limit. It would be perfectly normal to write more than you can actually say and then start cutting back or rewording parts to make it shorter. That's not "censorship." If you're cutting down an acceptance speech, the more off-topic stuff is naturally going to be looked at critically. I'd expect there to be multiple drafts with different portions cut out so it's not so much as a "full" verses "cut" speech but which version of cuts was the final version.
