Apple is also overdue for a consumer class action lawsuit for overbearing and overreaching control of consumer owned devices paid in full. Apple blocks apps like free open source Retroarch because it's emulation but yet allows paid VMWare, Parallels, etc. It's my device and Apple has no say in what I can or can't run on it.
You may own the hardware, but you only have a license to use the software. By using iOS, you are bound by Apple’s terms.
