Was Ashley Dupre Serious?

So I tuned in to 20/20 last night to see the interview with former call girl/escort Ashley Dupre, and I must say that I found myself very annoyed at that chick. Can someone tell me why she agreed to do the interview with Diane Sawyer if she was gonna refuse to answer the juicy and important questions?? When Diane asked Dupre the killer questions about what type of "client" the ex governor was, she responded, "I have been legally advised not to discuss that". Dupre then proceeded to give that same response several other times through out the interview. Instead Ashley wanted to discuss her daddy issues, and the fact that she felt abandoned by her father when her parents got divorced. Why on earth would we give a flying crap about that stuff? The only things we care about are facts like: how much money she got from the governor, how often she met with him, and whether he was her"difficult"client. That girl came on the show and tried to talk about being in love with a married man, and getting betrayed and left with lease of a couple thousand $. Homegirl got it twisted into thinking we were interested in those minute details. Anywho I give Diane and "E" for effort because she was very respectful to Ashley Dupre and she tried her best to get the goods for us. But it seemed like a waste of time.
