IANAL, but AFAIK:

Remember, all of you, that RA having used a reversed key does not legally entitle Apple to yank the app.

It *does* entitle them, under the DMCA, to sue those who did the original reverse engineering. If that's RA, then so much the worse for RA. But iff, as RA says, they have stuck to the letter of their agreement with Apple, then Apple is at risk of an antitrust investigation.
