IMO while it's more noticeable than Glass's single pixel it's still a concealed camera.
also, i'd say there's a general cultural trend of becoming more and more comfortable with less and less privacy.
How? If anything, the lense-less frame with a bulge on the side is very noticable.
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.
people are emotional, visual creates.
