I believe his main goal is turning Twitter into something of an "everything" site where he's looking to combine the likes of Facebook, Instagram, TikTok, YouTube, Discord, and Venmo/Paypal into a single service. I don't know if it was his goal when he bought it or if it has any chance in hell of working, but that's something he at least said (while probably drunk) fairly recently.
My first thought was an all-in-one "life subscription," kinda like how you can buy those iPhone + Apple One packages, but with Tesla (I don't know if Tesla has subscriptions to them -- but I'm sure they do), Twitter Blue, and Starlink. It's pretty dystopian and hecka freaky.
Yeah I saw that and cringed. Why would you give Andrew Tate money. It removes all plausible deniablity and proves that you want people like him posting on your platform.
