Thinking about it, I might have misunderstood what you wrote a bit. What I read was that you trust people, but then you also don't. That's not really a fair reading of what you wrote.
That being said, I have seen "patterns" with open source software as well, so I'm hesitant to agree on trusting it. But that's a different problem.
I also know how little hardware, microcode and firmware can be trusted, so that doesn't help either.

Thank you for the clarification. I certainly could have worded my comment better. I agree with you on that we should never trust open-source software blindly. That said, we can at least audit it, along with every new patch, which is impossible with binary blobs. That is why, I personally think, open-source should be preferred, for free and non-free software alike.
