It’s not hard to envision a potential business case
Musk, being Musk, will find this amusing and start auto-tweeting "Kill" videos of Tesla's racing with other cars on the freeway."104 Z06 kills on the West Coast Today!".
Self tweeting coming soon - self driving by the end of next year.
Musk’s job as CEO is to work in the best interests of the company. Using the company's resources to buy/build a completely unrelated entity for his personal gain is most definitely not ok.
If he wanted to do what you’re saying (enrich Tesla with those features), Tesla should be buying Twitter. The scenario you're presenting, by the way, is exactly how Facebook/Meta acquired Instagram. However Facebook acquired Instagram, not Zuckerberg personally.
But he almost certainly acted against the interests of the company he was hired to shepard and committed a civil offense against the shareholders.
Remember that SpaceX and Tesla do have a common VP for material engineering, Charles Kuehmann? It makes sense for them to share knowledge on materials.
In the same way, there may be a cause for sharing software engineering resources/know-how between Tesla and Twitter without actually merging the entire companies into one behemoth.
Actually, it's worse than that. They're working for a different, private company, one which happens to be owned by the CEO of TSLA, who has a legal and fiduciary duty to the TSLA shareholders.
You assume that money is not changing hands and that it’s off the books? Where is your evidence for that? You are making that assumption based off your own confirmation biases.
Nobody on here knows the details, this is just a rorschach test.
Sometimes I wonder if people genuinely stop and listen to themselves before they hit the reply button.
