No such vision exists. “Twitter 2.0” is still vaguely about free speech, somehow making lots of money from verified users, and also WeChat-of-the-West style payments (as if anyone would trust their money to this company).
Of all the problems I see with what's going on, this isn't one of them. Most of the current internet (and beyond that as well) exists solely on the premise that we give away power freely, with no expectations of proportional responsibilities in return.
If Twitter survives and, somehow, flourishes, all it takes for people to forget and sign up is a benefit to them, and blaring you opinions into a bigger void may just be enough already.
Not sure that even Mr. Musk can fix that.
