Perhaps a refined fan theory would be, taking the Vok into account and the limitations of Tetetraan 1, is that the Vok CAPTURED a Sky Spy (if there were, indeed multiples, which is dubious but let's assume that for a moment). The Vok then use the information and then THEY are the ones who manipulate the DNA of humans to inform their experiments. The ability to hack into Teletraan-1 via a Sky Spy would explain the Vok's knowledge of how to manipulate Cybertronian technology without the need of explaining their backstory...and maybe even enable their ability to scan Cybertronians for information (like when Primal is scanned and the Vok use Unicron's head as a visual reference via Primal's memory banks). In the end, Teletraan-1 itself just seems relatively limited in its abilities that the OP would like for it to be. But if you introduce the Vok as the primary manipulator, there's a chance that Teletraan-1 may have been an accidental accomplice.
