The article mentions two tests, in both of them the AI was released.
I'm thinking, this might be an interesting plot twist...
Eh. The conditions of the simulation aren't liable to come up in Shadowrun. First, AI's aren't "developed", so you can't have one that was developed in the AI Box - they just Emerge, though they may at some point be captured. However, the simulation is about the possibility initial release of a transhuman AI from an AI Box by an individual who has both the ability and recognized right to make that call, and in almost all cases a runner wouldn't have to second.
A captured xenosapient AI could convince the runners to free it, certainly, and its motives could turn out to be different than they thought - but as a plot twist, that would be no different than any ordinary person or a free spirit doing the same.
