The problem here is that you are erasing history. Imagine someone going into the town square and yelling something profane. That can never be unheard, people will never forget. There will be record of it. Twitter is the only authority that can validate that a tweet actually happened. All other archival services can be considered questionable and easily manipulated (albeit unlikely).
