When I was an android user, I would sideload every now and then. Not one did I pirate. On iOS FOSS apps pretty much don’t exist or are buried among forks that add mountains of ads and garbage.
On the App Store, they restrict away the kinds of apps that have a ton of value. For example, Microsoft can’t release their cloud gaming platform as an app, instead we have to use a neutered pwa.
Just give me freedom and don’t treat me like a criminal or child because I want to use apps that mommy Apple doesn’t approve of.
You cannot use an iPad as a developer platform. There’s no Xcode or Compiler, providing one is against the App Store policy so those apps just don’t exist in a meaningful manner.
