I'm pretty sure they said they're partnering with everybody that they possibly can. I also don't know what you mean by "just partner with postmarketOS." It's basically a project to create a fully-free Android-compatible distribution (or rather the fully-free low-level elements that would support this), and postmarketOS is not Android. I also don't have any idea why you think that they wouldn't be talking to everybody who is reverse engineering phones to get OSes on them.

I really do not understand this comment at all. I don't understand the weird judgemental tone, and I don't understand that people have reacted to it like there is content there.
