I'm not arguing against piracy. It's obviously not stealing. That was my first point.
My whole thing is that embellishing the obvious factual statement that "piracy is not theft," doesn't really drive the point home any more effectively. I find this specific argument needlessly clunky when the first point remains true in any context.
I would assume that it operates in much the same way that other forms of addiction do.
Mental illness, personality disorders, insecure attachments, trauma, social isolation and specific genetic factors are the usual suspects as far as predicting addiction go. I don't suspect that social media addiction is much different.
