Into Darkness was just partially Orci, and it was still crammed with 9/11 nonsense. Imagine the Space Benghazi flick we would have got with him in full control. Perhaps the magic Khan blood would have made Kirk autistic, as part of the film's anti-vacc message.
Roberto Orci is a hardcore conspiracy theorist, and also one half of an extremely profitable writing team. He's best known for co-writing some of the crappiest blockbusters of the last decade, most recently Amazing Spider-Man 2. He co-wrote the last two Star Trek flicks and was signed on to direct Star Trek 3, but apparently the studio despised his script and he refused to alter it.
Roberto Orci, the shitty writer behind Star Trek Into Loose Change has left the project, with Edgar Wright now in the running to replace him. Orci sucks and is probably legit insane, I can't see anybody being disappointed by this news.
