Well, Elon Musk just sent Twitter employees an email saying it's worth about $20B. He paid $44B for it.
I thought maybe 10b was what it was worth. And he could have gotten out of it by paying a $1 billion cancel fee, something like that. It appeared his ego prevented him from considering that. But it all goes back to him signing a terrible agreement in the first place.
I'm not sure why people are still repeating that. No, he couldn't, that fee would have been due if external influence would have prevented him from completing the transaction (e.g. the government banning the sale somehow).
