how can Steam possibly get hit with antitrust when Apple and Google are allowed to do whatever they want with their app stores while controlling the hardware/OS?
However, AFAIK the final appeal battle at the US supreme court hasn't happened yet.
They just aren't as high proile as Epic v. Apple. Probably for good reason given the shitshow that courtroom was.
Epic lost on every other anti-trust fight vs apple except this one - every appeals court has upheld Epic's freedom to direct iOS users who want to buy cosmetics for Fortnite into the Epic store, which violates their agreement with Apple.
That said from other comments here I’m not sure how accurate/true that claim is.
