It is rather fashionable to dislike Google. Google is supposed to be tearing down the fabric of society, stone by stone. Even though several other companies are busily chipping away at the same stones - Facebook, Microsoft, the Social-hype-du-jour, etc - they don't get the type of special attention Google gets.
And now Google presents the penultimate society destroyer, creating a distributed panopticon of world-wide proportions. It is not relevant whether Glass actually will do all the bad stuff the detractors claim. What matters is that Glass is 'proof' of Google's bad intentions.
In a few years, other companies will create their own augmented reality devices. Microsoft will adapt their Kinect 3D-scanner to fit in a pair of spectacles, Apple will do the iGlasses, etc. Microsoft's product will be met with ridicule because it makes you look like those dorks from Weird Science. It will map your environment, helping Microsoft to expand their own mapping efforts to all 'public' areas, inside and out. It won't map your private quarters, unless told to do so by the relevant authorities. Apple's iGlasses will be hailed as the next coming of your favourite prophet, finally it is done right, opening up new markets, just working seamlessly together with the other iTools, how do they do it. Some people might grumble over Apple doing all those bad things which Google Glass was supposed to do but hey, it is their product, they can do with it what they want, if you don't like it, don't buy it - the same argument used to meet criticism on other parts of their walled garden. For some reason the iGlasses don't make you look like a dork, even though they look quite similar to Microsoft's product.
