My view (not OP) is that Elon will break the company and get it to fail.
He does not understand that Twitter is an ad driven business which also means PR is critical or you don't get advertisers.
Most businesses that tried to pivot from ad driven to subscribers have failed. One that tried to do so in so dramatic a way? Never heard of it.
Elon is not doing a simple management style change, he's changing everything with next to zero money. Unlike a startup, a company the size of Twitter cannot compromise what is feeding them without failing quickly. A startup can survive on small VC funding for a pivot, Twitter eats millions of dollars to just operate.
