Which one would you choose and what would you do? (Other than kick out anyone who uses pronouns). Me personally I'm torn between two:
Sony: not so much for PlayStation (I'd just shut down and fire everyone at California HQ and remove all censorship, make 18+ material require a password to look at) but anime access, cutting off any American influence there and getting better rates for studios would be in the best interest.
Bethesda: would fire Todd Howard then force them to go to Id and get a better game engine.
Assuming that I have complete control and my order have to be followed, and I can't be removed through physical force?
Disney or Alphabet. Arguably Alphabet would be the bigger one to topple, as I believe I could clean house almost overnight and gut the anti-Christian, anti-American measures and employees quickly.
Or as a meme answer, let me take over the US Government. It's basically a media company these days, really. Give me two terms of uncontested power and every command I issue being followed in both letter and spirit, and I think I could buy this country maybe another century or more before the corrupt commies start sneaking back in.
