As a Fairphone 5 owner, 6 seams like a downgrade to me, with it’s USB 2. I don’t care about whatever refresh rate they have, USB alt mode is way more important to me, also dropping audio jack was bad enough already.

Well, the audio problem is not going to be worse with 2.0. USB 2.0 can deliver 480Mbps. Audio data rates are in Kbps. Even at 192kHz, 24 bui studio recordings it is only 4.6Mbps. Stereo audio is easy from a digital perspective. Also, USB 2.0 is MUCH less susceptible to bad hardware design, bad cables and dongles, and bad shielding. A single twisted pair at low speeds and minimal negotiation is much simpler and almost never drops. In a joystick design I did, I had a 20cm long untwisted pair in testing and it never dropped at all.

USB 3.0+ (and especially external display capabilities) is an order of magnitude more noise sensitive, impedance variation limited, and susceptible to bad design. If you use a non, twisted cable, it won’t even negotiate USB 3.0 and will only work with 2.0.

That being said, USB 3.0+ for large file transfers and an external monitor desktop mode would be so much better, but I guess not many people use those.
