Is a girl, or a woman, sitting spread eagled really that disturbing?

Today I heard about a young photo model whose parents are sueing the clothing company for which she had done some modelling. see here.
I don’t want to ask about the case itself she being underage, morality, etc., but I am curious about what you think about women who are sitting with their legs spread eagled (clothed, I add)?
What is wrong with it?
Is it always sexually loaded (in the eyes of the people who are offended by it)?
I mean, legs crossed or legs opened, we all know what is behind the fabric, but that doesn’t mean a woman is inviting the onlooker, right?
