To be perfectly fair, people are extremely displeased with x86 hardware back doors. So it’s not exactly the same as the way you present it.

Though I agree overall, I’ve read the code (and compiled) the operating system I use day to day, but that seems to be uncommon apparently, and I’m not above just trusting some package maintainer.

That said: trust is still earned, and easily lost.

There’s a lot to indicate lost trust in Microsoft (despite the fact that I did say in my parent comment that it’s separate from the point).
