The most important factual inaccuracy is that Billy did not have the Donkey Kong record while Steve was pursuing it.
According to those posts by Walter Day, Steve wasn't even pursuing a record - he already had it regardless of the Mr Awesome debacle. Who honestly gives a ---steaming pile of meadow muffin--- if Mr. Awesome helped him with his board? The fact that TG uses that as a defense destroys all of their credibility right out of the gate.
In the end, who gives a crap. I don't know either of the guys, I will never meet them in real life. It was a MOVIE. No need to get all worked up. The only person I feel sorry for in the whole mess is Brian Kuh - the poor guy is the king of all nerds and probably can't show his face at Funspot anymore.
