The first source you linked is run by GrapheneOS community members so it's slightly biased: https://privsec.dev/about/

Why would GrapheneOS be biased against F-Droid? It's not like they have their own app store. (They have "Apps" but that's not any competition.)

There was some drama between the two communities unfortunately. I can't remember the exact details.

I'd bet good money that Madaidan was Daniel Micay
