Apple devices aren't free computer systems. Apple owns the devices, not the users. They gave up their freedom when they bought a computer that doesn't give them the keys to the system. They have little choice other than to accept whatever conditions the big corporations impose on them.
Thankfully, iOS does not represent all systems out there. Android systems allow installation of apps from any source and PCs traditionally have no limitations on which programs can be executed by the user. Better alternatives to these abusive "official" apps should be a selling point for these free systems. A perfect example of adversarial interoperability:
