The problem is up-streaming kernel patches shouldn't be a Mobian thing or a pmOS thing, it should be an entire community working together for it (and IMHO, Pine64 should be leading the part to making a healthy community and contributing to it). For at least the OG Pinephone, that community has more or less dried up. Many of the original folks that wanted to help moved on to other devices (or just left the community as a whole. The situation for upstreaming kernel patches hasn't changed in years, and I honestly don't see that situation changing as is.

I would recommend reading for some background:

Also, frankly, when we get a response like this: https://mastodon.social/@CounterPillow/110589778080526844 from a Pine64 developer when we worked to port over the PineTab2 to Mobian, it really doesn't make me want to work with them.
