Twitter could not back up their claims regarding bots and fake accounts. Nor could they back up their claims that banning accounts was non-political. I don’t blame him for backing out. They do not have as many real accounts as they had indicated. That’s why just after his offer, many fake followers of those on the left just disappeared. They were trying to “clean” things up. Twitter will eventually go the way of MySpace, as will Facebook.
I suspect his plan all along may have been to make that a matter of public record.
He knew he wasn’t going to go through with the deal from the get go. He had many conservatives salivating that he was going to set things right and he got massive publicity, which was the real goal all along. I’m not sure why so many people saw him as some kind of savior.
