My email was obtained, and my credit card #. I used to subscribe to Stratfor to get another (more in-depth, geopolitical) perspective on the news.

Stratfor has sources whose anonymity (like with Wikileaks) is important.

If indeed the breach does reveal people who have helped Stratfor obtain information for its stories, it will be akin to if the group had hacked Wikileaks and outed Bradley Manning before he was caught by the government.
