Despite all the other compromises with the FF6, I still was ready to buy it until I noticed the USB-C 2.0. Which means no Android Desktop and significantly slower data transfer than the USB-C 3.0 in FF5. The linked Discussion thread from the Fairphone forum has some interesting additional points.
Is this a dealbreaker for you? (It is for me, I'm ordering a different phone today..)
It is a downgrade for sure but if it's not something you use then what does it matter. Fairphone is a tiny company and they felt this was a good place to cut on costs
