$2100 for me. I figure since I bought the car before the price hikes I can justify it. It seems a lot of people just don't care about steam so they probably don't lose out, but it's a game-changer for my use case. They'll probably lower the price in the future like they did with MCU2, which was $2500 to upgrade and then later $1500.
I also agree about the small claims court thing. Tesla never promised steam, they promised Witcher 3 and Cyberpunk "in the future." Which they technically haven't lied about. They'll probably do the math, port Witcher 3 for x amount of money, or replace everyone's MCU unit for free for likely substantially more money. They'll just port 2 games, make you buy them only for the tesla, and move on.
