It is also a fact observable to anyone outside any court of law that while Google sells phones, their main relationship with Android is as a vendor-neutral OS developer that licenses the OS out and takes responsibility for its maintenance and a services provider that required favoring their own software and services over that of their competitors as part of their agreement with phone makers.
Apple makes and sells phones, including the OS, and services for those phones including the App Store. They’re not telling Samsung they must favor Apple services in order to receive an iOS license because they don’t license iOS to Samsung for Samsung’s phones.
Google and Apple both chose their own business plans here, which is their right, but it also put them on different legal footing when Epic came calling in Court because in theory, Android was supposed to be an open ecosystem that third party app markets could thrive on and it just wasn’t that, in particular because Google was putting their thumb on the scale.
