I doubt Apple could demonstrably prove damages before the civil statute of limitations expires. This is a nonstarter in court, and furthermore this is not negligence by the FCC. You do not have a right to keep your FCC filings from leaking under all circumstances, and the FCC has not assumed a civil obligation externally to your rights to do so. Government agencies do not sign NDAs when corporations submit technical documents to them. The Federal government has no obligation in statute to keep them secret, you asking them to is a polite suggestion to the FCC and holds no bearing in law. Even if you could prove damages, trying to bring a case under the Federal Tort Claims Act against the government for this would be a nightmare in any administration, and there's no way that the Supreme Court would cede the idea that the government has an absolute obligation your filings secret forever under pain of civil penalties. It's an embarrassing clerical error, but it isn't a tort.
