It's called slash and burn tactics.

When Napoleon and Hitler both marched on Russia, the Russians burned all the crops and houses to prevent the invaders from using it against Russians.

If it wasn't a white hat move, I'd wager they just slash and burned any and all evidence they were working for DARPA/CIA.

When the Whistleblower investigation asks for the files, they can say they were all vaporized in this "error."

Then when Durham gets to them, he'd have nothing to work with and a previous investigation telling his own investigation that there is nothing to investigate.

I'm holding out hope that Space Force just annexed the Facebook backend and server space, leaving them a shell of their original Lifelog mission statement.
