Not really what happened. It all started because the fans wouldn't stop asking about timelines. I doubt anyone even would have mentioned it if we didn't keep on about it. In fact, until the release about 'true prequel to TOS' I think it was all question answers at panels and the like. And nobody ever said it would 'match up completely'. Right back in his first answer on the subject, Bryan Fuller said it would obviously look different because, well, 2017.spend six months before the show starts going out of your way to assure fandom that it's Prime Universe and will match up completely,
