At the end of ST:DIS 2x14, Spock recommends that
all officers remaining with knowledge of these events must be ordered never to speak of Discovery, its spore drive, or her crew again
in order to prevent the experienced series of events from unfolding again.
This left me deeply confused.
I understand that the data
gathered from the Sphere
was instrumental in
Control gaining self-awareness
Thus, the plan was to send
the ship along with the data, which is magically locked to the ship, off into the far future where it is out of reach.
So, what in the world is Spock's recommendation supposed to achieve in-universe?
Given that various methods of time travel are known in the 23rd century, it is conceivable no-one should know the data is on Discovery. But about the rest - surely, Starfleet cannot just deny the existence of the Discovery's crew. And what does the spore drive have to do with it, anyway? As far as I remember, it played a significant role during several events of the Klingon war, which are definitely noted in Starfleet's historical records, but it was completely irrelevant to Control's rise.
