I don’t think buying a phone should be a belief system. A phone should simply work, and the main responsibility of the producer is to make sure that it does.
Of course, Fairphone is special — that’s why we were all willing to pay twice the amount a comparable phone would have cost. However, if some customers are frustrated and are asking Fairphone to listen to them, maybe we should actually do exactly that instead of lecturing them or telling them to get lost.
(By the way: I am very, very happy with my FP6. No reason to complain whatsoever.)
