Exactly what other use would someone have out in public for a pair of glasses that silently and stealthily record the world around them on a whim?
Google was literally bashed for exactly this same reason with the Glass. Its not that people dislike the idea of portable recordings, that's what we have action cams for - it's the desperate attempt to conceal a recording device into glasses.
The market is basically only vloggers and perverts, and the vloggers are perfectly content with wearing way less creepy action cams.
