Yeh, probably not random Twitter or Facebook photos. My experience is that people think that they (co-)own images in their family albums or images they have ordered from a photographer. But if they aren't the authors, then usually it's not theirs to decide the copyright matters, whether publishing the work under a free license or not. Which is why the new wording confuses me more than the previous. Maybe "taken by you" instead of "took yourself" would do.

Copyleft, as much as I understand, is a special case of copyright where some of the author's rights are still preserved.
