Uhh, I have an extended family member, who not only uses it, but now also tries to get other people to get into it. Since I was familiar with this practice ( and the issues it makes worse ), I noted those to him in an attempt to both politely decline and, hopefully, spare him, and society, some future problems. Without going into any identifying details, he didn't take it well ( and I don't think I got on my high horse ).

Anyway, I think some level of blame is warranted.
