Or rather, Peter Thiel…

(I’m aware of Doofenschmitz, just pointing out who is the non-fictional villain here)

If you know the folder where the configuration of FreshRSS is stored on the various devices and the structures are the same over all devices: it should be possible.

True, since Fairphone’s focus seems to be on fairness in the hardware. I wish they were better on the software side as well.

I don’t recall it was hard to install IodéOS on a Fairphone 4.

Running a Fairphone 4 with IodéOS (another de-Googled privacy focused Android) for close to two years now and I agree that it’s a capable phone which doesn’t limit myself in any way.

As you mentioned the biggest downside is the camera, which apparently has something to do with the firmware.

Edit: regarding the headphone situation: I’m using Austrian Audio (=former AKG engineering team) Hi-X25BT headphones, which are noticeably better than pods or cheap headphones and have been running well over a year now. They come with both (mini-)jack to USB-C and USB-C to USB-C cables, but I haven’t tried the latter yet.
