I audit software updates by looking at developers announcements and community discussions (in social media, forums etc) before installing updates. Then, even if developers keys and computers are compromised, I would notice something is wrong. * No, of course that I don't always do that. I even don't often do that. But I did do that in the past, and I'd like to have the option to do that.
