I keep seeing this idea everywhere. Buy a Google phone and install another OS.
It is completely absurd to fund the exact adversaries you are running away from, while consuming, without contributing a dime, merely a piece of free software. (It is only a small piece of freedom because none of the hardware is free, and some binary blobs [incl. potential backdoors] will still be present in the alternative OS no matter which one it is.)
This is unsustainable, terrible, damaging advice. Stop giving it.
