When the command comes to destroy evidence, the company already unravels. The CEOS and upper echelons do no longer hold the power of career life and death, instead they are just "visibly" pawns in the larger game of society, playing "prison" or "no prison". In that moment, even the most loyal individual realizes that the game is lost- and that deleting evidence that proofs your innocence, would increment you for nothing.

Thus that command - is never followed. There are always copies of the bad shit everywhere. The underlings are not that stupid.
