There’s plenty of good restaurants where you don’t have to look or act fancy. I’ve spent 1k on a meal without alcohol for my GF and I in a place where you fit in wearing jeans and a t-shirt and you can talk about whatever the fuck you want with your friends and nobody cares. You could make anyone discover tons of new types of foods without having them feel bad about who they are…

Twitter is private, there’s no public shares anymore. The number you found was his stake before he purchased all the shares and before Twitter was taken off the markets.

Yes you need to have 50%+1 share to have complete control over a company.

Twitter probably still has shareholders, but that’s between Musk and them. Think about Shark Tank, when they say “I’ll offer X$ in exchange for Y% of the company.” Well Musk had to get the money to buy Twitter from somewhere.
