The website formerly known as Twitter doesn't actually need any users or activity anymore, it just needs the perception of users and activity. Doesn't even need to make money or be a business. It could be bots all the way down and it would serve its purpose, which is a platform to host Musk's personal views (news outlets need something to link to when they quote him after all), which are varied opinions relating to the virtues of white supremacy, imperialism, capitalism, and techno fascism. I say this with 0 hyperbole.

It's a playground for him personally, essentially a real-world sandbox RPG where he gets to choose the NPCs, he gets to make and enforce all of the rules, choose the outcomes, all in service of soothing his massively damaged ego.

If he has to unleash a child raping mecha hitler on the world to do so, then so be it.

Twitter also doesn't need users to fulfil Musk's goal of destroying a key factor in many (all?) people-powered movements. Occupy Wall Street, Arab Spring, BLM.

And I'm sure that's a factor in why people like Larry Ellison and Saudi princes stumped up some of the money.

The problem is that the media still uses X in it's reporting, and people still use and link to it. If we just stopped using X and stripped it of any legitimacy, it would fall off pretty quickly.
