I suspect they meant the patterned clothing that confuses cameras.

I am against constant surveillance and these are huge privacy violations, especially because it seems very unlikely they're storing the media exclusively locally. Also, the fact that they can be more discreet than many other options for recording is concerning.

The first two ads I ever saw for these were of a guy using them to quietly cheat at, IIRC, a board game; and of someone having a conversation, only to realize the other party was recording it. They looked like legit ads, but I'm not sure how anyone could think that was positive press.

All that said, the number of people advocating violence in response is alarming. Depending on the environment, I feel the appropriate response is to ask the wearer to remove them and then, if they refuse, remove either yourself or them from the situation. Obviously no one solution fits all situations and there may be situations where violence is warranted, but it is surprising to me that it seems to be the default.

edit: Recently started using a new keyboard on my phone, had to correct a word it chose for me. The meaning I was trying to convey was not altered.
