I wonder what (if anything) the repair techs thought when doing it. If a disgruntled employee wanted to maximize damage to the company (without regard to personal consequences), this surely looks like one of the ways to do it. I think it's still more likely that they just did it because they found it funny, but this is a kind of insider risk for companies that is really hard to defend against.
