I think to truly break out of US controlled operating systems is to be able to run the proprietary apps/programs, that people depend on, on an open source operating systems they don’t control.

While ideally people shouldn’t be dependent on this proprietary software, due to unchecked monopoly behavior, consumers don’t have many choices, especially in mobile.

There has been success with Valve and the Steam Deck. While they are still a US company, they have hugely pushed forward running Windows games on Linux to the point where you don’t need to use Windows unless you want to play games that require anti-cheat.
