Parag successfully forced the sale of the company at 2x it's valuation - enriching every single shareholder on the board, which is what he was made CEO for.
If Twitter wants to fight a legal contract for severance packages, it's their funeral. It's not just Parag, most Twitter employees were fired without severance which breached their contracts.
So who's really the dumb guy here, the guy who sold a company at 2x valuation, the guy who signed an agreement to buy it and then violated it's employment contracts, or the guy commenting that the person who sold it is an idiot. Definitely seems to have outsmarted Elon.
