It's a public policy exemption. A greater good call by a grateful society would not punish TC for its crime/immorality if it deemed the leak to be of sufficient value to public interest. That's a risk the publisher/whistleblower takes but it's only a risk if there's an enforcement/judgment process in place, or else TC faces no such risk and can publish anything it damn well likes without having to estimate the value to the public interest of its actions.
Which, quite frankly, is what they frequently failed to do in the past.Their judgement is suspect, to me at least, even if they've never been punished.
