Yes, she is a very public embodiment of everything I hate about modern 'celeb' culture but she is going to suffer a very painful death and leave two children without a mother, no-one deserves that regardless of how self publicising she has been.
Regardless of how she came about her 'fame,' how she has dealt with it has been very shrewd, she has made a living out of being a non-entity, I suspect many are jealous that they couldn't do the same or have the same opportunity and those are the ones that snipe at her, she has had a privilaged adult life despite/possible because of her chronic lack of any outward talent and it's easy to put her down because of it.
That she is under a showbiz spotlight right now is actually par for the course for her, and why begrudge it? It will ensure a good life for her children, and that is the most important thing.
