If you only look at the bang-per-money factor, the FP can only lose, of course. From my point of view, I would say that most other phones are overpriced for what they pay the workers and for the environmental impact they have. And for the fact that they don’t offer a long warranty like the FP and may have to be replaced sooner.
But the discussion is probably going nowhere at this point. Unless Vlad would be willing to add a broader point to the list, which he/she could perhaps call “karma factor” 
Even though Fairphone may be lame or unreliable in many ways (as a company) they would probably be the last of the whole list to intentionally pull the plug on unlocking.
