It’s worth questioning whether or not this information was intended for us - to retrieve it, their damaged and battle-weary vessels are destroyed. The footage seems to be from a Drifter perspective, meaning they’re possibly battle recordings. But the situation preceding the revelation of not unrelated distorted recording is what’s making me think:
It’s important to remember that the Drifters used our common language in their messages from “Dr. Tukoss”, albeit imperfectly. If this data was meant to be readily given to us, they would have made things far more simple - that, or it’s this is some sort of test of our capabilities.
