I am not snarking on you at all when I say this, but I have a strong feeling that a VERY large percentage of spouses of those leaked probably thought the same thing.
I guess I've just seen enough people who have been 100%, completely blindsided by MANY actions of their spouse - ones they would have literally sworn on their child's life wouldn't happen...and it did.
I'm happy for you that you trust with 100% certainty that your husband isn't on this leak/hack - but I have a feeling that there is eventually going to be this type of leak for just about any facet that is considered "juicy" enough to bring down any group of people.
Personal topics that come to mind:
HIV
Adoptions
STD's
Abortions
Paternity tests
Any medically prescribed drugs - anxiety/depression/etc.
Credit report debt amounts
The list goes on...none of these are anyone's business whatsoever, but boy would people have a field day knowing some of those things about others.
