Yeah, let's not forget that in another timeline the sphere data helps Control wipe out all intelligent life in the galaxy.
Not really an accurate statement considering that initially, Control didn't get its hands on the Sphere Data.... it evolved entirely on its own.
Remember that the Sphere was put in Disco's path because of Burnham's mother... and back then, the Sphere was literally in its dying moments before it downloaded itself into Discovery.
I just don't see how Control would be able to get its hands on the AI data in general if the Sphere was destroyed in early Season 2 somewhere in deep space.
Control only learned of the Sphere Data after it was on board Discovery (probably via official channels) and then targeted Disco to get the AI data so it can evolve faster (aka, Control was actively downloading specific information, but otherwise it didn't have real help from the Sphere Data itself - which is odd considering that the Sphere Data could have put up firewalls around itself much like it did when Disco crew tried deleting it to prevent bits and pieces of itself from being copied by malicious AI - which may work temporarily, but it would still provide time for the crew in general).
