I don't think it's anything like a "lynch mob" - people died as a result of lynch mobs.
There have been very few personal attacks on CN; yes, there is perhaps more pleasure being taken than is "nice" in the fact that the solo tour is not selling well, but that is because people are glad to see that BULLYING isn't being supported - not because they want to crush CN in particular (well - they didn't, but perhaps her post-LW behaviour, and her awful son's vile tweets, have hardened attitudes).
TBH - I doubt her tour would have been a huge hit anyway - certainly not the career-boost she was hoping for. She isn't a singer, though she likes to think she is, and she and LN have been very fortunate to coast along on the little talent they have for as long as they have. They have been lucky - a lot of showbiz success depends on luck - some artist have the personality and good sense to grasp their chances and make the most of them; others don't. Even more don't get the opportunities, despite working hard and being very talented. As someone said earlier - Them's the breaks.
The poor sales for the tour aren't welcomed as CN's career death knell - they are welcomed because it shows that viewers are sending a message that they will NOT tolerate bullying behaviour.- and hopefully a message that this sort of car crash TV has had its horrible day. The viewing public are not idiots - often we want light entertainment and debate of issues from a "man-in-the-street" perspective, rather than an intellectual, or political, or economic one, but that doesn't mean we want playground spite and viciousness.
