Snapchat-loyal press have been well trained to highlight the spinning LEDs and not question the privacy angle. Perhaps they're "ok" with it because clips are shorter and it's not the big bad G.
IMO while it's more noticeable than Glass's single pixel it's still a concealed camera.
People wear sunglasses on the top of their head, behind their head, etc. all the time. When they do that with Spectacles, they won't be directly pointing at the people they're talking to. So there's a potential for privacy-respecting etiquette with Spectacles- I have them on my forehead, I can't be recording you. Dunno if that was ever possible with Google Glass.
probably the same in practice, but glass really looked like it was trying to be inconspicuous / disappear, which made it much creepier. specs are so clearly conspicuous and not trying to hide that it makes them seem more harmless.
also, i'd say there's a general cultural trend of becoming more and more comfortable with less and less privacy.
to me, it still looks stylistically like it's trying to disappear, like it wants to blend in and become unnoticable. it doesn't seem to be making an obvious "i'm here" fashion statement like the specs.
obviously it's a subjective emotional statement and difficult to support or refute, but i really do believe the vastly different appearances of the two products probably has a lot to do with the different reactions they are receiving.
