Yes, it was an obvious mistake. But no, he was not obligated to buy Twitter. There was a way out from the start--only that way out would cost him a billion dollars. That ought to seem like a bargain now, and many folks (even me) thought at the time that paying the billion would be his smartest move.Buying Twitter for $44B was an obvious mistake. ..... He was contractually obligated so followed through.
It's pretty obvious by the way Musk has devalued Twitter (and Tesla as well in his efforts to buoy Twitter) that a billion one way or another doesn't mean much to him. But this guy you hesitate to criticize, John, made an obvious mistake in offering to buy Twitter, and made a second obvious mistake by not taking his lumps and moving on. And why, exactly, do you hesitate to criticize him?
(Obviously, I used the word "obvious" too many times in this post. Thankfully, that obvious mistake will not cost me billions.)
