I think I'm reading this blogpost correctly: Mobian devs working on maintaining Linux kernel support for Pinephone painted themselves into a corner with tech debt, and may not be able to continue porting new kernel updates. Pinephone Pro runs a different chipset with wider community support, so it's not affected.
I didn't see any communities or articles talking about this, so either it's not a big deal, or nobody is talking about it.
More than likely very few people own a pinephone, and the few that do don't read pinephone news. Thanks for posting this.
As for me, I'm not buying another pinephone/GNU+Linux compatible device until both the community and the manufacturer get their shit figured out. I bought the PInephone expecting it to one day become more useful to me, so I guess that's on me.
