Agreed. The Google implementations are there for folks who absolutely cannot go without certain apps only available from the Play Store. Upon installation, all that’s there is the OS with the necessary apps (camera, phone, browser, etc) with the security on these individual apps additionally patched.
With the sandboxing of Google Play and Services AND the option to further house these apps from the Play Store in a separate profile, you have a perfectly working device that the individual user can customise to their needs.
Its a great project and a real asset to the FOSS, privacy and security community against big tech/govt surveillance.
The phone is only as good as how you choose to set it up and use it.
With the lack of any other viable option, I struggle to see the point of the arguement.
