I did not want to get into this, but you're simply spread falsehoods.
> GrapheneOS doesn't ship integration of proprietary services like CalyxOS, whether that's WhatsApp or Google services.
We do not ship anything proprietary. We ship microG, which is "A free-as-in-freedom re-implementation of Google’s proprietary Android user space apps and libraries." - see https://microg.org/
We ship an integration with WhatsApp in the Dialer, which is entirely open source code. It is based on the existing contacts mechanism (anyone who has WhatsApp or Signal on any Android will see entries for those in the Contacts app - that is what we expose to the Dialer to make it easy to use those to make end-to-end encrypted calls.
In fact, WhatsApp is not listed by default, it only shows up if you have it installed. We believe that end-to-end encrypted calls are important, and while this would leak some metadata, if one has it installed already presumably they're fine with that. The network effect is strong!
In fact, you're the one who's promoting your approach of being able to run the proprietary Play Services - and yet you say you don't ship integration of proprietary services. Which is it? You can't ship Play Services legally anyway.
> or example, they give special unattended installation privileges to Aurora Store and F-Droid.
Aurora Store does not get unattended installation permission, it never has. It can only update installed apps, which is what Google is allowing in Android 12.
F-Droid Privileged Extension is extended, and both that and F-Droid have received security audits in the past which haven't found issues - and the Privileged Extension itself hasn't changed much since then. We're very careful about making any changes there.
It is one thing to give constructive criticism to projects, it's another to attack them directly based on falsehoods.
