The show has been on for like 17-18 years. It is time to go anyways when you think about it. That is why I say it is really no big deal to her. She will find something else.While i agree with you to some degree i think we have a different metric for what qualifies as "brought down"
I think its better to say that she wont be "popular" many of these people such as the ones you mentioned, coast by how they can... not how they want to and thats a blow. Both to their overall income but also growth as an artist.....
In short
Fewer people will have a quote by her on their stone.
Work on her gorilla or elephant thing she has wanted to do for all her life. She is fine.
