I don't follow you. Lots of people put stickers over their cameras, not just hacker news posters, and furthermore, I think we all agree they have good reason to do so, it's not just posturing to look cool. (Also to me, "I bought a $2700 computer and I can't even trust it not to photograph me" is the opposite of cool, but I digress.) Also, I trust my chair, my bicycle, my car to a great extent (made in 2001 though), and quite a few other kinds of technology. So I don't understand what you're saying here.
