I checked today my aurora store as I run a couple of basic apps that were coded requiring GSF use (google framework services). Aurora store proposes me to update Google play services(Gps) with its last version, the update comes from Google LLC, apparently.
I run anonymously Aurora store, I don’t have any google account.
To add some technical explanations: microG has the same package name (com.google.android.gms) as the official play services, in order to replace its functionalities. On this basis, Aurora store thinks that google play store is installed and proposes an update. This update could not succeed if attempted, as the signatures of the two apps differ: so trying to update is harmless. Blacklisting it is the best option, to avoid continuously seeing it (with failures when updating all installed apps).
