GrapheneOS has never in recent time encouraged the use of Aurora Store. It is actively discouraged by the community and officially by the project, due to severe security issues with it, as well as the fact that it has no privacy benefit over using sandboxed Google Play Services on GrapheneOS, which is the recommended way of usage.
You can search for Twitter posts by the project account mentioning Aurora Store. If you view through a couple, you will see that it indeed is not being recommended to be used, but to stay far away from it.
You can also join the Discord or Matrix channels and ask for more information there.
The only places that recommend Aurora Store are those that either spread misinformation or have been misinformed themselves. It is very difficult to get accurate and good security/privacy advise on the Internet. Places like YouTube or Reddit should best be avoided completely, as most advise and information there is misguided, inaccurate or outright dangerous.
The gist is:
- Aurora Store does not properly verify downloaded apps (dangerous)
- Aurora Store has no working or reliable auto-updates (severely dangerous)
- Aurora Store does not avoid any Google tracking, due to many apps on the Play Store bundling Googles libraries with them, which run on your phone even if you don't have Play Services installed and collect the same amount of data, as if you would have Play Services installed directly. (Which is not much to begin with, due to the strong app sandbox)
Play Services run completely unprivileged and without any elevated system integration or access. You can use an anonymous Google Account without phone number or PII with it.
If you want to really avoid Google or Play Services as best as possible, you cannot use any apps from the Play Store at all, this includes Aurora, as it doesn't make any privacy benefit or avoid any tracking, as described previously.
Be aware though, that it is basically impossible to avoid Google as a whole, in the software world.
