What utter nonesense. Just because the GrapheneOS Team doesn't do free work to support devices you like doesn't mean they prevent you from doing it. It's still 100% opensource and you are free to port it yourself to whatever device you please. The entitlement of people that want the grapheneos project to work for them for free is insane. Fucking hire a dev to work on this for a few month yourself if you don't like the device support.

I explicitly said in the link that the lack of resources is a good reason for not supporting other devices, but it's not their stated main reason.
