You should probably state in your title this is about GrapheneOS being proprietary or not. Unfortunatelly I can’t help you
Their official response is in the replies
GrapheneOS and CalyxOS are both great projects. Don’t see the point of this fight and it just weakens the privacy and open-source communities.
agreed, this kind of petty drama doesn’t help.
Would also like to add this: Please remove all code from Vanadium and GrapheneOS project members · Issue #2141 · bromite/bromite · GitHub
I don’t thing it’s fair to say Graphene is proprietary (at least not yet), but they are really self-centered it seems.
