I’m in the embedded market and have kept my first FP3 8 years it was pretty outdated technically but its fairness is intact (in fact it’s still in use).

It is not a FOSS hardware indeed, it isn’t like a samsung either, it is I think the top of the game among existing consumer solutions.

Fairphone and samsung are absolutely not the same kind. I want to point fairphone is officially distributing /e/OS which is a niche of 2-3 brands. This company that is nowhere in size close to samsung also engages hardcore in device repairability making its phones be a flagship. If anything just let them be successful and tempt others to follow their lead. I would love graphene os to be better supported but just don’t put all the strain on the one doing good.
