FP4 isn't even officially released yet (and when it is, there's delivery time), while devs don't get the device before release. They need to buy it just like the rest of us. However, the previous Fairphones ran all kind of OSes, including the ones I mentioned. In fact, I believe Fairphone was the first smartphone to run on some of these (IIRC pmOS, UT). Given the device gets support for 5 years (including software updates) that's gonna be a while where devs can support it, and where it gets (supposedly) firmware updates for the embedded chips as well.
