Well logically you should complain about faulty buttons and be unimpressed by working ones. But people don't work logically so it's the same effect as wearing too tight shoes or the childrens' story "A squash and a squeeze", the relief you feel from something bad returning to a normal level is palpable and can actually feel better than just having things work in the first place.
Like you, I think it shows that if you get the important stuff right, then people will be very forgiving of your faults, while still being harsh about similar level faults in competing products (which perhaps get a different set of important stuff right for other folks). People are funny that way and while I find it interesting, I don't think people should celebrate it any more than placebo effects should be attributed to new medicines.
