As I near the eol of my daily driver, I'm considering a Fairphone, but what it's missing is a folding card holder, like the Satechi wallet stand for iPhone. Putting the phone in horizontal mode on a table and using a bt keyboard is how I do a lot of my writing
It would be good if Fairphone could make a product that meets GrapheneOS requirements, but they measure the tradeoffs between security, usability, and cost (to do hardware and software things) differently. Each team is free to make the choices they deem fit. If only the intersection of GrapheneOS and Fairphone users were bigger, market forces would push them towards a common vision.
There's is no bad blood here, it's merely that fairphone doesn't meet the required standards for them to be a target the graphene team is interested in supporting offically. There's nothing preventing anyone from porting it themselves and nothing preventing fairphone from porting an inferior version of grapheneos to their phoens.
