Perhaps the programmers you're talking about don't like people very much, and would prefer not to have them polluting our photos!

Or, to say the same thing much less cynically: as an introvert I use photography as a solitary activity in order to recharge - so I naturally gravitate towards people-free locations when I have the camera in hand. None of what you say is false, of course - but when I pick up the camera my goal isn't necessarily to produce the most meaningful or poignant image possible, nor even to produce something that necessarily resonates with anyone else.
