Fairphone is clearly not forgetting any of their devices. They are upgrading the Android version of an old device (FP1) that they are not producing anymore!
That’s part of the result of spending a whole year looking for a completely-free laptop, compatible with Debian as-is (without the non-free packages) and below the 1000€ limit (Purism is just too expensive for me). Glad to share it and help! 
That’s a complex topic, there are various kinds of fairnesses! FP’s main objective is human fairness: health and working conditions; second, ecological fairness: repairable modular phone, software updates; third, software fairness: a Google-free OS, FP Open sources, community OSes. All of them are user-looking fairnesses, IMHO.
That’s my analysis, at least.
