Well, we can take three of those off because they were shunned for political reasons. Shannon Dougherty was apparently just obnoxious. Amanda Bynes appears to be actually mentally ill. The only one that really relates is Billy Squier (public wasn't ready, yet, to see a "rocker" dancing around like an idiot), and he didn't exactly have a multi bazillion dollar empire at the time. I think Madonna and Britney are better comparisons--the times they've gone over the top trying to be controversial and been mocked for it. They both still have careers.
I disagree. What is bad publicity? It is publication of a fact or facts or attitudes that are either negative or that are spun negative or that cause a negative reaction. Paula Deen lost sponsors due to the
publication of what what many felt was a racist attitude. The Dixie Chicks lost fans due to the
publication of a speech her fan base abhorred. Sinead O-Connor lost fans due to the
publication of various things including statements Catholics were offended by and also just bizarre behavior that turned many people off:

If not for the publicity surrounding these events, few fans or sponsors would have deserted them. (And BTW, I am not judging their various statements or beliefs by listing them. I'm simply pointing out what bad publicity can do).
As far as Amanda Bynes and other child celebs, what does it matter if they are mentally ill or on drugs or whatever? How does that excuse them from being affected by bad publicity? You stated that no publicity is bad publicity and I'm showing that's untrue. When celebs receive bad press,
for whatever reason, they can and do suffer from it.
Shannon Doughtery's antics were publicized and caused her to lose fans. The studios reacted to that.
They always do.
Re runs of Pee Wee Herman's Playhouse were dropped by CBS after he was arrested for masturbating in a theatre.
AFLAC cancelled Gilbert Gottfried's contract after he made horrible jokes about the tsunami victims.
Remember Michael Richards? No one else does either at the moment.
Lance Armstrong???
Again, it doesn;t matter what the behavior is. The fact is that there is such a thing as bad publicity and it can hurt a person's career. And again, that's why celebs hire publicists. It's also why the studios totally controlled the stars' lives in the 30-s through 50's. They owned their stars but they controlled publicity as a result.
Mile Cyrus got mad bad publicity as a result of her antics last night. And it could actually harm her career. So yeah, we're talking about it but that's not necessarily always a good thing, which is the while point.
