Yes, anti competitive practices are good for business regardless of geography.
Americans may be the biggest offenders but the pro-competition rules should apply to all.
Personally, I have the skills and interest to write a custom OS for my phone (Linux, custom DE, and waydroid for Android compat) - but it's literally impossible to due to anti competitive practices (I can't reverse engineer drivers and clean room driver development is practically impossible).
Similar story for my router, my "smart" TV and arm64 MacBook pro (or even an arm64 surface laptop).
