I detest Apple and would happily switch to a timeline where they never existed.

That said, I do not think this is the way to fight them. Just do not make apps for iPhone, or pass the 30% Apple tax to the Apple fanboys. They enjoy being submissive to walled garden overlords and paying for the privilege, so give them what they want.

These are perfectly valid options. Create value for more open ecosystems if you want to hurt the closed ones.
