Possible to avoid Google's future open source ban on Android devices?

If I am already using a rooted but proprietary smartphone (Samsung Galaxy S23), downloading my apps from other sources than Google Play, how would Google be able to control what I do with it? If necessary, I could just stay on my current OS build as well. All in all, while politically and philosophically, Google's new policy is bad, I don't feel threatened by it with my current understand of the situation and technology...
