My theory is he's pulling a zero requiem. He watches anime, so he's probably watched code geas - it's a very popular futuristic anime after all

First he became the symbol of the useful billionaire, the Tony Stark guy who's going to save humanity, because he's a futurist with the power of money. He learns everything about his companies the way a kid learns every stat about their model car, and actually does weirdly good as a hype man. He gives off the awkwardness of an engineer

After he meets Trump in the white house, he realizes how close we are to the brink. The fact that billionaires own all our media has led to existential danger, where truth doesn't matter and money speaks

So, there's a plan for a group of individuals to buy Twitter. There's text logs of this - he was invited into a group planning to buy it together for the good of humanity, but it took all of 5 minutes for them to start carving holes in the ideology, so he backs out.

He then announced the intention to buy, trapping him in a situation where he was forced to go through with it... He struggled a bit, but not that hard really

So then comes the plan. He takes over, and every two weeks or so, he makes an impulsive decision showing zero understanding of the company. One idiotic decision at a time, spread out long enough to remind people "I'm still here, and I'm still ruining a major platform for public discourse!"

People start to realize he's actually kind of dumb and pretty racist... Even the fanboys are getting quieter and quieter in defending him. It's becoming public knowledge he isn't a Tesla or spaceX founder, he came in as an investor when they already had a plan

He's burning up half his fortune in an effort to show us all what a billionaire is. He's not a businessman, he went to college to learn programming but doesn't understand the basics of software, he's hated by pretty much everyone in his personal life, and every company he's tried to build from scratch has been a disaster. He lies constantly, in ways that will eventually come to light.

This guy was able to buy Twitter, just because he invested in a company that bought and sold PayPal (after kicking him out for being unbearable). He's showing us all that billionaires are an existential danger to mankind, even the "good" ones.

Or, maybe he's just having a midlife crisis and has a compulsive need for attention. One of the two.
