I currently have Play Services and Store installed for notifications. I have not signed into a google account and get all my apps through Aurora or F-Droid stores.
If Play Store can already see all of the apps I have installed regardless of the source, I am not gaining any extra privacy by using Aurora store. I could just use the GOS recommended approach of using a throwaway google account and get all of my non-F-Droid apps from the Play Store. Is this the logic behind the recommendation?
