Why would that mean it could compete with a Pixel which generally has none of those goals?
Pixels have long term availability of official parts for repairs and also official repairs.
Unlike Fairphones, Pixels have very good updates over the long term. Fairphones do not provide anything close to decent updates and it greatly degrades over the lifetime of the device. Fairphone 5 and earlier have an end-of-life kernel without security support. The devices start out lagging months behind on partial security backports and a year or more behind on full security updates which gets worse over time.
