@lordmatt @quixoticgeek Nobody can. AIUI Hasbro's board can issue a buttload of new shares (about 5x the current issue) if they want to, and a takeover bid would drive the price through the roof before they had to do that to hang onto WotC. (Also, if you're worried about Musk, Hasbro's CFO is ex-Paypal and hates his guts.)
Hasbro are pretty shitty but they're not going to sell the goose that lays the golden eggs to a fascist (or anyone else). And the threat of open games keeps them in line.
