For example:

• You MUST use Apple’s own apps (iMessage, Phone, etc.) as well as Apple’s own App Store
  • To be fair, the EU is doing work to solve this particular issue…but most of the reforms are only for EU customers
• You have to use WebKit when developing a browser for macOS iOS and iPadOS, you can’t use Gecko or Blink
• iOS apps must be developed using XCode IF YOU WANT TO PUBLISH IT ON THE APP STORE, which is only available on MacOS…

That last one is weird. Why can’t you compile Swift outside of MacOS (i.e. third party IDEs)? Why can only XCode do it?

edit: Gecko and Blink based browsers are available on macOS. I learnt something new today. Not for iOS or iPadOS though. Also, Xcode is only a requirement for publishing in the App Store. You are able to compile Swift in any OS. You’ll just need to distribute the app via sideloading and/or third-party app stores (in the EU)
