I think the reason you keep reiterating this is because once you realize that there is no legal justification to go after Google for this move under current US law, the only real solution becomes obvious: new legislation, and you really don't want that, because you know it will apply to Apple devices as well, which would be The End of the World.
If you want to see what the solution to this problem looks like, take a look at the bipartisan App Store Freedom Act: https://www.congress.gov/bill/119th-congress/house-bill/3209...
(This is before Apple/Google lobbying efforts result in either the death of the bill or a bunch of exceptions allowing companies to do "notarization" or "developer verification".)
