@[email protected] The idea that Play services is needed to use Google services or that there’s something special about what it does is wrong. Everything it does as sandboxed Google Play on GrapheneOS can be done by other apps. It has no special access or capabilities. It does not give absolutely any additional access that’s not already available to the Play code in apps. If you want to avoid Google Play, you have to only use apps not including Google Play code, such as using Molly FOSS instead of Signal.
