Because he tells the truth, he's banned from Tweeter.  He's better off without them.  There are myriad other ways to get the word out to people without twitter.  You know, people DID survive (literally and figuratively) BEFORE tweeter was even a "thing" and it's just too damned bad we can't go into reverse and be back to that time.  We were a much more honest world before googLE, tweeter, amaZOn, instaGRam, etc., ever came on the scene.  As far as I'm concerned those places are a complete waste of valuable time when people SHOULD be doing other things, such as taking care of their children, etc.
