That comparison shows "Deblobbed? Yes" for GrapheneOS. That implies they've replaced (most of) the blobs for wifi, bluetooth, 5g chips etc.

Is that actually true? It's such a big deal, and I see little to no work being done on this front.

Anyone have any idea what GrapheneOS actually deblobbed?

Nice! Thanks for the link. I noticed they didn't mention MOCOR OS (for the new Nokia 3210), but then I remembered that that's not an Android version. I'll see if they can add it somewhere else.

Unrelated, but this led me to find gnuclad, which may be somewhat externally maintained and is used to create the cladogragms.

This is a great resource! Thanks
