Because no intelligent, technically competent person has ever had a reasonable criticism to make about Glass, or the track record of the company making it, in regards to privacy and participation with NSA surveillance, or of the potential downsides to adding even more ubiquitous, fine-grained surveillance to the modern world.
I mean, Glass is no more ominous than cellphones. It's just a cellphone strapped to your face and pointed right at everyone you're looking at. No one would be creeped out if you held your cellphone out in front of you and recorded everything going on. It even has a little light that shows when you're recording, which is controlled by perfectly trustworthy software.
Bunch of Luddites, they all are.
Basic human decency and social norms haven't changed as much as you think. Walking around talking to a computer strapped to your face, staring at a little screen in the corner of your eye, is profoundly anti-social.
Are you implying that doing these things with a cellphone is now alright?

But many, if not most people have learned how to respect people around them while owning and using a cellphone.
It's a shame though, Glass hate is coming from the old school, technophobe camp. While it _is_ a clunky, underdesigned, underpowered piece of tech, we should aim for sleeker, more powerful, more useful head-mounted computers… instead for no HMC at all.
