Don't want to support conflict mining, but are okay with Android on a Qualcomm SoC = Fairphone
Don't want to run a non-free OS or integrated baseband, but are okay with manufacturing in Shenzhen = Purism Librem
Which you shouldn't, for obvious reasons.
Ethical products don't spy on users. Fairphone uses Android, so it isn't entirely ethical.
Because customers want Google.
The bootloader is unlocked. If you want to install Fairphone Open then you can. That's an Android version sans Google/OpenGapps. [1]
If you want, you can also install different firmware. Examples: LineageOS (with or without OpenGapps), LineageOS + microG, SailfishOS, UBTouch.
FWIW, the SoC is a SD801.
From leaked LG LK code it shows that's definitely where their bootloader unlock keys lived [at one point a couple of years ago].
Since the Librem device is a different beast, though, I wonder what their bootstack looks like? Super curious now!
