All I see is a bunch of drama. Daniel Micay is also no longer the head of GrapheneOS.
IDK maybe beyond the wall of text there is some actual technical criticism, but I'm not going to sift through a bunch of unrelated pictures to find it.
GrapheneOS very recently reported two CVEs affecting Android, with one not affecting GrapheneOS due to their mitigations.
GrapheneOS has many features which are clearly visible to users and don't really exist elsewhere - eSIM without Google Play, sandboxed Google Play, additional "Sensors" permission just to name a few.
Edit: I watched the Louis Rossmann video, https://www.youtube.com/watch?v=4To-F6W1NT0, and he also only talks about drama related to Daniel Micay (while clearly not saying anything negative about the project on a technical level).
