If the reporting is faithful (big if) then Yusupov is demonstrating neurotic, paranoid and controlling tendencies. Maybe that's just his personality; if focused correctly I imagine those traits could benefit a startup's growth. Another plausible explanation: his regret over what happened to Vine after selling it to Twitter has led to obsessively avoiding any chance of making similar "mistakes".
