It’s gonna be tough avoiding the reach of the us surveillance/intelligence state. The hardware is easy, afaik no phone is actually manufactured in the us. Some may be assembled in the states but none of those use domestically produced components.

The reason it’s so hard to avoid the reach of the us intelligence apparatus has mostly to do with Israeli/eyes integration. Often that information sharing is built into the very networks, governments, law enforcement and data markets used all over the world.

Your phones os could be free from the untrustworthy grasp of the vile American developer, but it would still have to connect to infrastructure with built in law enforcement backdoors, use programs that make use of American servers if not directly employ American programmers and receive transmissions from services provided by Americans.

If you’re serious about removing the influence of the American intelligence apparatus we call the internet from your life, a clean break, permanent logoff is the simplest solution.

Be wary of people suggesting you switch to handsets and software developed by prc companies or other obvious choices. There’s a trend in the west to blacklist imei (the unique device numbers used to identify phones when they make network connections) ranges unique to those devices. You might buy some hot shit new xiaomi and find out your provider refuses to connect to it or requires you to install their surveillance package first, landing you back where you started.

I’m using recent iphones, pixels with graphene and other stuff.
