With this question asked, I'd like to build on it and ask what options exists outside the realm of google given their recent bullshit.

For those who know, tell me about the pine phone, fair phone, anything else like this.

When google fucks shit up in the near future, I would very much like to hold on to the ability to side-load apps using obtainium and f-droid indefinitely. Are the pine phone/ fair phone reasonable for this? What pros and cons am I looking at?
