I don't just blame Elon; I also blame the Twitter board for forcing the sale. Elon wanted to back out of the transaction but the board insisted. The blame is shared by both.
Freaking greedy idiots. Twitter had its faults but now it's a total mess. I hope lessons were learned from this. I doubt it.
Don't conflate greed with fiduciary duty. The board did what it was supposed to do, maximize shareholder value.
