I don't have time to explain or argue with people now, but nobody in their right mind disputes Oz as being an excellent CV surgeon. I introduced my uncle to him when he needed several valves replaced 8-9 years ago. At that time, I wouldn't let anyone but him do valve work in NYC. I have no idea how his volume has been the last couple of years and he is likely operating a lot less with all his other things going on. But, do not think for a second that he isn't a) a very smart guy and b) top top in CV surgery.
As for the other stuff, meh. I haven't looked at it nor do I care about it. I don't really fault people for wanting to make money or be the face of something. Maybe medical school/residency has jaded me, but the American public doesn't want to listen to doctors talking about real issues. If they want to listen to someone selling bs, good for him to make money off of it.
