Pretty sure this has been mentioned already, just can't find anything about it. In a joint move, google seems to have ended open source development of pixel device trees and drivers at the same time they announced that no non-verified apps will be supported. No coincidence this comes at the same time that ID checks are becoming commonplace online. Very disturbing trend, likely tied to governmental pressure about surveillance coupled with their own desire to control what gets to be put on the devices we soon will no longer own.
How will Graphene survive this? Might have to go to a Linux phone at this point, or just not have a phone at all. I refuse to go along with this shit.
