for me, the biggest issue with the fairphone is that they attempted to embrace everything: modular, sustainable, fair trade, etc
their competitors do none of that, so the quality/cost ratio turns out way off and that prevents their market share to grow sustainably (pun intended). the few people I know who use it, are the profile that is used to do sacrifices like that (like buying sustainable food at large markups, etc) but that’s not feasible or desirable to the vast majority
imo they should have picked a concept and perfected it - preferably the modular part which is the best thing you can do and brings tangible value to users. then move on to the other things… that’s a great cautionary tale about trying to be the good guys in capitalism, the system is not in their favour
