I think he knows it is a money pit that will never be profitable so is intentionally trying to kill it. It will never make him money only cost him money. He can’t just shut it down without seriously damaging what credibility he has left. Seriously, what are his options to stop this ‘money leak?’
Could he though? I don’t think he is that smart. He has smart people running his other companies, but he is running the show at twitter. I think this is us seeing him fail when left on his own.
