Also, that tech team might in another large organization (not McDonald's) in another part of the world, where any work they do has to be budgeted for, agreed on, spec'd, tested, and released through a tedious process. Someone might be casually thinking "hmmm this doesn't seem quite right" but there would be a dozen hurdles to jump from that suspicion to getting anything done about it, so they keep quiet and move onto the next project. They might never even know or care if their code went live.
