Supposedly Gabrielle Burnham lured the Discovery to the Sphere exactly because several previous timelines had already led to the Sphere puking its contents on parties that then delivered them to Control. Control gaining the data was the robust default setting - perhaps because the Sphere was dying inside UFP space, and Control had very good access on all intel within UFP space.
However, supposedly Gabrielle also painted herself in a corner with all the overlapping time meddling she was doing. It took her a while to realize that Armageddon was the result of Control getting the Sphere data; she then set out to do something about it; and when realizing she could do very little, she had already contradicted herself fifteen times and risked collapsing everything into a chaos. Possibly several more obvious ways to deal with the issue, such as going farther into the past and steering the Sphere to die somewhere else, would have done more harm than good to local history overall. Also, giving the data to her daughter to worry about was a kind of "I have a hammer, so this has to be a nail, no matter how bent" move: Michael was an agent she could rely on, sort of, even if the Federation was full of objectively better candidates.
