I guess there is one more important bit that author is missing. Twitter also let's anyone retweet very old postings out-of-context and don't even show some warning like "this was posted N years ago" tells me they are not interested in de-escalation. There are a lot of years-old tweets that can be used to attack a person. And no people don't have to specifically delete their archives or press some "I was wrong" for solving this problem.
