I think they essentially questioned why is she 'famous'; is it because of outstanding technical ability, or because of the way she presents, and unwisely chose to try and disprove her technical ability.

The question still stands to some extent though I think. Using 'sex' to sell yourself is accepted in music, film, fashion and so on, but perhaps not in technical fields, and, actually, as I think about it more, I'm starting to agree a little bit.
