Fair enough. I said “huge” because I guess some people care a lot. I personally don’t and have been on security preview releases since they started releasing them.

Not exactly. GrapheneOS has an OEM partner and has early access to AOSP changes that aren’t public. A huge downside to that is that security preview releases can’t be open source until after Google makes the code public.

GrapheneOS isn’t dying. There’s an OEM partnership in the works and they’ll release devices with support for GrapheneOS in a year or two. GrapheneOS still provides updates and while the changes have made some things harder, the project is still going strong.
