This didn't happen in the movie, and therefore isn't "canon."
Ah, in that case I was misinformed.... Still haven't seen the movie.
If Spock didn't tell Starfleet, how did they find Khan? Supposedly nobody goes to that part of space any more, and the Botany Bay
isn't visible at a distance...
Spock's statement that he would never divulge his knowledge to influence destiny in the new continuity
...An obvious and blatant lie, considering he divulged plenty of his knowledge to this explicit end in the first nuMovie!
