Most anti-google move: buy a second hand pixel, they receive no revenue on the device which is (assumed) already highly subsidized by google so that they can profit off users' data, then you use their subsidized hardware without running their spyware OS. Google only loses money in this scenario, it is a great protest.
Have you seen those prices? I don't think the devices need subsidising at all. How else could competitors, who aren't selling off your data, offer it for cheaper?
