A self-portrait is a portrait you take, you know, yourself.

If I didn't take it, then it's just a picture of me. That I told the stupid computer about "myself" does not make the data it compiled a "self-portrait."

Sounds like they're trying to blame the user for what they're doing with the data. Yes, we're responsible for trusting the damn things, those too many of us who do, but that's where our responsibility stops.
