Forum:Tali's comments in the briefing room

In Mass Effect 2, when you finish Tali's recruitment mission and, like everyone, she's greeted by Jacob/Miranda in the briefing room, she expresses great concern at working with Cerberus.

Among her concerns was "Cerberus" thinking it's a good idea to do experiments involving the Thorian and breeding Rachni.

My question is, was this meant as some kind of retcon or was it actually a subtle reveal that ExoGeni was actually a front for Cerberus operations, as were the operations on Noveria?

This seems like a pretty big continuity issue, unless I've completely overlooked something somewhere.

Can anyone can shed some light on this?
