I don’t know but this guy has it down.. they are indeed acting like Microsoft in the 90s and no one seems to be paying attention
The judge in the original trial was paying attention. She said that Apple's market share wasn't quite large enough overall to be considered a monopoly at the time, but she left the door open for Apple to be sued for antitrust again in the future should their market share increase. That was affirmed by the appeals court, and the Supreme Court didn't change that ruling. It somewhat came down to the fact that consumers have other options for playing Fortnite in a mobile fashion, such as Nintendo Switch or via cloud gaming options which the judge thought were currently adequate alternatives.
The Microsoft situation in the 90's is different from this situation. Apple literally never nags someone to use one of their apps or puts up unreasonable barriers to prevent use of a competing app. Apple never really did anything to prevent Fortnite from releasing on or being installed on iOS. On iOS they require distribution of apps through their App Store, which pretty much every developer including Epic was ok with.
Epic's real beef was with Apple not allowing alternative payment methods to the App Store, which is where they should have placed more focus instead of overall antitrust. The judge in the case was very clear that Apple is violating California law by not allowing developers to inform consumers of alternate payment options that bypass Apple's IAP system. If Epic had focused on that as the reason Fortnite was removed they probably could have forced Apple to allow Fortnite back onto the App Store with the ability to advertise that in-game currency was available elsewhere. But Epic went nuclear option. Apple was appealing this ruling to the Supreme Court and lost, meaning that other developers can now sue Apple under the original ruling to allow alternate payment links in-app.
