Your obviously supposed to notice him. Is he really there or was he shopped in on purpose?.
Whoever uploaded the original image did so for a reason beyond stopping you from going down the Snowden tangent. I believe this high rez image is for 'normie' consumption. clickbait. A game to make you question things. Women eat this stuff up. They love family portraits.
Real or not is irrelevant. It is designed to stimulate asking questions like "who" then "what if" then "why" then "who"again. Try showing it high rez to your spouce / girlfriend etc. Watch how fast they work. Again you don't even have to believe it's real. Can a painting hanging on a wall make you ask questions or stimulate a narrative in your imagination although you know it is an illusion?
Another wasted morning!
