Apple isn’t going to win the leak war. What’s leaked is leaked; there’s no getting it back. Journalists can legally report on it and they know that. It takes 5 minutes to create a truly untraceable Twitter account using Tor, or Whonix if you’re extra paranoid.
Leaks these days are simply news outlets and blogs all regurgitating the same unsubstantiated rumours. Cut off the leak at the source, and you stem the tide.
