Fine in the crib, out in the open at a critical moment when your kid runs into your arms, screw image quality, you want that moment captured and with active kids there's about 2-3 of these moments every day. "the best camera is the one you have with you".
If I don't like something about my hot frog pot, I'll just switch to the Apple glasses when they come out [1] ¯\_(ツ)_/¯ . Zuck doesn't have much room to maneuver without shooting himself in the foot.
My larger point stands, not all who wear cameras deserve to be maligned.
