I think that broadly speaking, the anger directed at FP when they announce something new is a little more personal than most other consumer rage. We tend to tie our identities to some extent to the products we use, which is an unhealthy habit that only leads to heartbreak - but in the case of FP, it comes with a history of actually participating in this thing that started off as an experiment and has now become as serious a smartphone company as any. So I have a little more understanding for the anger people feel about FP than I would for similar anger found on, say, an Apple forum.
The people who bought an FP1 participated in an experiment that could easily have failed, as many thought it would. The people who bought the FP2 bought another experiment, a phone that requires little bits of paper, battery shims and, occasionally, mild torture to keep it going. The people who bought an FP3 bought a more stable and feature complete phone that was however still a lot chunkier than other smartphones, and even it still has its issues. Every time, we bought these phones with the understanding that we were participating in something that wasn’t yet profitable or perfect, but better than all the rest in certain important ways.
All of that to say that a lot of people here feel more like collaborators than customers, and not entirely without reason. That said, now that it seems FP have arrived at a smartphone that closely matches the average feature set and form factor of its contemporaries, whilst including fair materials and sustainable design features… we should be very happy about that, because that has always been FP’s charter. The FP4 is not for me, but I have high hopes it’ll be for everyone else.
