As bad as the article makes Gwyneth sound, I think it's very possible that the comment Gwyneth made was only part of a response to a question posed to her by the interviewer. It's very possible that the interviewer asked, "So, having married a celebrity yourself, what is your take on the Pitt/Aniston breakup?" and she very sincerely answered, "You know, I think it would have been a lot easier on Brad Pitt and Jennifer Aniston now had they not talked to the press about each other and everything to begin with, because I know relationships can be difficult under the limelight of Hollywood," but the writer of the article saw an opportunity to create a fuss over it and decided to omit the other parts mentioned.
All I'm saying is, we all don't know just what happened or what she meant, so we can't all jump to the conclusion that Gwyneth is a pretentious whatever-you-want-to-call-her. However, as I don't follow her or know her personally, I understand I could be very, very wrong. But I'm just throwing out another possibility here...
