It's not a religious position.

It's a chain of trust, as an individual you can decide where that trust begins and ends for you, but it's impossible for you to be at the forefront measuring every possible variable, and being an expert in every field, conducting analysis of the data.

At some point you need to defer to people who know (or at least, you believe they know) more than you.

It's like with our computers spying on us. Yes you can inspect the code, yes you can check the signatures of the code running on your machine match the code as listed, but then what of the OS, what of the drivers, what of the micro-code, firmware, hardware, etc etc.

It's an impossible position to reason you out of, because you are living in a completely zero trust world.
