Yeah. Before OneUI 8, you could set up a custom ROM on a Samsung phone too. Short of that you can disable google services. Use non google apps from F-Droid or Aurora Store. You can also use ADB to uninstall system-level APKs. Though the only way that I know of to fully de-google is to install a different OS.
Not all android spies on you. Have you ever tried GrapheneOS? It’s very secure and pro-privacy. Technically it’s not android (if you really want to nitpick), but you need a Google Pixel to run it.
Not to nitpick, but I believe the term you’re looking for is “Neo Nazi”. The Nazi party ended in 1945. Though you’re right. If the US government was completely taken over by Neo Nazi’s, it would almost definitely cause WWIII.
No.
