Your best bet is to lower your own expenses and rely on AD revenue. You start making people pay for the service and they’ll just leave to another competitor who makes they money off of data mining. All it will take is for Elon doing something super fucked up and enough celebrities to leave twitter to a new competitor that appeals to the younger generation and it’s done. He’s not making his 44 billion back anytime soon and definitely not be the time a competitor starts up that lures in user base.
