There are other options as well for why he wants to take apart Twitter:
- revenge Peter Thiel-style against "librul" ideas that "made" his daughter trans (or his ex-wife Grimes date Chelsea Manning). Twitter is the biggest forum there is for left-wing and progressive people, and it was/is in financial duress, which made it a perfect target.
- the Saudis, who are the main financial backers of the deal (and even the dozens of billions they paid are petty cash!), want him to destroy Twitter, which has been an incredibly useful tool to organize protest and spread information about government violence
- Musk, like other SV billionaires, thinks they are the best that God has sent to Earth and what they do and want is best for everyone. Unfortunately, as a result he doesn't realize that large markets like Europe see it precisely the other way around.
- Musk, again like other SV billionaires, sees technology as the one and all solution hammer against society's problems. Hate speech? Have algorithms "moderate" the platform, instead of booting out abusers and putting those who cross legal lines behind bars. Fossil fuels? Invest in electric cars (and sooner or later, nuclear fusion vaporware, mark my words), instead of investing in renewable energies and public transport. And again, he doesn't realize that wide parts of the planet do not follow their idea(l)s.
