Perhaps 'leaving' was a bit ambiguous. But denying the Illusive Man access to the Collector base, then telling him that he was now part of Shepard's team (rather than the other way around) seemed to me to suggest a fundamental break with Cerberus. Then various squadmates' reaction to my decision (including "You sure know how to make an enemy, the Illusive Man is dangerous" or something similar) suggested that the relationship was far from rosy. At any rate, it was clear that in my game Shepard had a fundamental disagreement with Cerberus' ideology - I'd like that to be reflected in post-game DLC, instead of characters making assumptions about Shepard that we can't combat in any way.
