Well, that's unexciting, but honestly not at all surprising.
Particularly with the security questions, I can imagine that as a celebrity if you're not careful it's exceptionally easy for someone to figure out the information compared to an average user without such a huge public profile of personal information available. Even security conscious average users know that it's the best idea to use answers that simply have nothing to do with the questions, and that is ten times greater for a high-value target with a lot of public information on them available.
While it's disappointing (if unsurprising) that a lot of celebrities weren't more careful, this does not, of course, somehow negate the crime of accessing and distributing private information. I'm not ever willing to blame the victim when a crime is committed--you should be able to make your password "password" and still have the right to privacy, because stealing information is still, nominally anyway, a crime.
