IMHO Elon is causing controversy to keep Twitter relevant. Amongst his many skills, he's a showman. Every little thing he tweets gets amplified by the media and places like HN. He needs activity to maintain relwvance and revenue. He's also become a diety of sorts for conservatives and IMHO likely trying to pull them back in after they left Twitter for other sites, or even for good.
You see a skilled showman. I see a petty billionaire hell bent on pushing through his way whilst trying hard to sell us on him being a good guy. And I'm not buying it.
