Perhaps if Glass was a little cheaper and/or offered more to a regular consumer (non-enterprise) it would have seen greater acceptance.
Placing enterprise on the same field as consumers, the security and piracy concerns are still the same. There is no real change there. Hardware improvements should always happen. So the only noteworthy change is the focus or target for its use.
The problem with the regular consumer market though is the issues they talked about above; lack of privacy and 'glassholes' believing they should be able to do what they want. The original google glass gave no indication to people around them when the camera was used for pictures or video. This allowed personal information (credit card numbers, cam-ripping movies, etc) to be easily gotten.

If you look into other articles about this, she claimed she was using google glass to pay attention to her speed; but was actually doing 15mph over while face booking; which was later stated after the court hearing. The ticket was dismissed only because they couldn't prove without a doubt that the device was on.
In industrial level usage, these issues can be controlled.
