> Grapheneos is fully open source and comes with 0 Google services.
And calls the open source microG a threat while encouraging people to install google mobile services, conveniently provided from their preinstalled app store, which most people will need for at least some of the apps they need in daily life, so everyone ends up with GMS installed in their main profile. A real bastion of freedom and choice.
MicroG requires privileged access. It also downloads and runs proprietary google code within this privileged context. MicroG additionally has very poor app compatibility and has had severe privacy issues in the past.
Sandboxed google play does not grant google code any kind of privileged access. It is confined to the same app sandbox and permission model as all other apps and can be installed and uninstalled like any other app.
Note that apps with google libraries grant google the same, unprivileged access google services gets on GrapheneOS. MicroG fails to meet the privacy, security, and usability requirements GrapheneOS has in place when it comes to google play compatibility.
So, you can pick MicroG, which is bundled, privileged, poorly made, has poor compatibility, and trusts an additional party...
Or, you can pick sandboxed google play, which is not bundled, optional, unprivileged, fully sandboxed, and does not trust additional parties. Oh, and you can uninstall and reinstall whenever.
It is evident which option gives the user freedom, and a choice.
