Comparison of Android-Based Operating Systems

GrapheneOS scores well and rightly so, but my main gripe is that they don't ship F-Droid and they actively steer users to Google Play and Aurora instead.

It's weird because the only AOSP app store that has any hope in hell of providing meaningful security and privacy to users is F-Droid, through its FOSS-only stance.

That's not to say that GOS shouldn't exclusively provide and steer users to F-Droid. There are good, practical reasons for providing compatibility to allow users to consume Google Play Services on apps that they need. I get it. I just happen to think most users in the know would want to escape that ecosystem.

The most important table is at the end, and manifestly only 2 brands are widely supported: fairphone and motorola. Plus google for the moment but since they stopped to publish their pixel specific source code, it will not last

Seems like a GrapheneOS puff piece considering all the qualifiers are aimed at GrapheneOS.

Even if you don't plan on switching from stock Android, Appendix 1 compares the various isolation alternatives - work profile, private space, and secondary users - all of which can be used with regular Android.
