Hey there, I’m sorry about this craziness. My comment was not really directed at you, but I was just quoting part of the original post that mentioned you.
I was trying to suggest that OP is confusing criticism of the GrapheneOS community with criticism of the OS. You make a good point and, as I pointed out, you were not criticising the OS, but the community. Not the same thing.
May I recommend OSS Document Scanner + Syncthing? Both apps are FOSS and it looks to me like that they might be able to replace what Microsoft Lens does for you with the advantage that you are free of Microsoft software.
