Jack Dorsey Is Losing Control of Twitter
Well, one would hope so.  Fortunately, Twitter doesn't have one of those "president for life" two-class stock setups like Google and Facebook.  The stockholders can fire Dorsey when necessary.The post-growth phase of a social network doesn't have to mean its collapse.  Look at IAC, InterActive Corp (iac.com, ticker IAC). They run a lot of sites - Vimeo, Ask, About, Investopedia, Tinder, OKCupid, etc. - have a market cap of about $5 billion, and keep plugging along.  They were started by Barry Diller, the creator of the Home Shopping Channel, something else that keeps plugging along.  Diller is still CEO. IAC is boring but useful.Twitter doesn't have to "exit"; they're already publicly held. They just have to trim down to a profitable and stable level, and accept that they're post-growth.
