I read the linked answer from the GrapheneOS account.
The fact that it runs Google binaries makes it intransparent (about that fact) and worse than sandboxed Play.
If DivestOS runs it sandboxed and only allows to spoof Evil Corps Signature, and the downloaded blobs are also always the latest, I see no problem with it.
The main benefits are the alternative backends supported by microG. There are no standalone solutions anymore.
I think it would be awesome to have google-less unifiedPush and UnifiedNLP for apps that actively support it. No spoofing, no play services. Apps requesting the rough (GPS) location will invoke sandboxed UnifiedNLP, that feeds the location to the OS which then redirects it to apps, thinking its the GPS location.
Same for UnifiedPush which is only supported by FOSS apps anyways.
I know this is a lot of work. I already donated a lot :D please do the same.
Having these as standalone solutions, not being integrated in the play stuff that I dont use on my main profile, would be brilliant.
A thought: network location is critical infrastructure. If GPS sattelites where just bombed, what then? Use Google or Apple? The situation is like that currently.
