Not quite. Having a QR code featured in a photograph isn't steganography since the existence of information is hardly hidden at all. Rather than hiding the information's existence what I'm considering here is how you could make it legally difficult to unequivocally prohibit spreading information that's in plain sight (think "Free Speech Flag" [1]).
