Nice try. PP may be a lousy CEO...but he's not outright stupid. Why would he sell a dime's worth of stock? He certainly knows the future of the company is brighter than when he was there, and since he's already been paid (far too much imo), I doubt he's struggling to make ends meet.
Did you convince anyone? It takes a #$%$ to liquidate at this level. PP isn't that kind of #$%$ if you read his profile. Joking aside, they probably have some kind of agreement with restrictions on his selling. And of course, he's still a founder, if I were him I wouldn't want to smother the stock, and maybe he can't even if he wants to. Good luck to you
