If you put yourself in a user's shoes that doesn't know what the issue was then that is still generic. As a user who doesn't know the story I'd be wondering:
- Did they get hacked and now some unknown party may have the contents of my address book?
- Were they selling my information to others?
- Did something happen as it relates to storage that mixed up or deleted information
- Was my data being transmitted in the clear
- Was mt data being transmitted without my knowledge or approval?
Two of those things did happen but the user doesn't know for sure. To be fair though, I think their statement was enough. They really don't have to go into more details unless the situation calls for it and it doesn't right now. Those who know get the apology they deserve and those who don't continue using Path as if nothing ever happened. Win win.
