This. Apple is a large enough, and competent enough, organization to investigate this internally. Some will say "but the people involved have a gag order, and nobody investigating, including tim cook or legal knows". This doesn't make any sense. People without a clearance are not obligated to keep it a secret, and can investigate for themselves. So either everyone competent to investigate this has a clearance and/or is gagged (i.e., many thousands of people) and if that were the case it'd almost certainly make to Tim Cook's radar. Or not that many people are gagged, and Apple has thousands of engineers that could be looking into this, and they found nothing. I find that much more plausible.
