How is that nonsensical? Trusting someone does not imply trusting anybody, and even less everybody.

I trust my mother; it does not mean I trust you, and even less the entire crowd here on HN.

I've stopped using Windows years ago because I didn't trust Microsoft anymore. I'm having minor trust issues with Canonical and Mozilla. I still trust Debian and Arch.

Trust is personal. Hard to get and easy to lose.
