Nobody is doing this. Calyx is taking a measured approach, as they see it, and is making commensurate claims: "CalyxOS is an Android mobile operating system that puts privacy and security into the hands of everyday users." Right on their website.
I am vehemently against absolutisms on security. Where that road goes is straight into a dick measuring contest and it's ugly. You only have to look at Moxie's terrible public behavior to see what the fallout from that approach looks like.
It's a poison in the security industry and it needs to be called out and stopped now. It rewards grown adults for acting like children. It's enough now.
