A man called Greg Pabich wanted to release an "official' version of Cheetahmen II, he used Kickstarter to help fund it. He asked the Nerd, the Game Chasers, and Pat the NES Punk to help make a silly video promoting it. It was put on James channel (as well as Pat's) and since he's the most famous of the three, people started calling him a "scammer", an "e-begger" and all sorts of names. A lot of people didn't bother to research and thought James was getting the money. Mike had to do a shit-ton of damage control, right down to disabling the comments.
Before that though, James himself started an IndieGoGo for the movie. His goal was $50k, but by the end fans donated 325k. Some people were furious that despite reaching the goal, it kept going. Makes me wonder what these people think of the Double Fine Kickstarter exceeding its goal in a few hours.
One user called "TheArchfiend" took advantage of this, and like Fox News made multiple videos with distorted facts and lies. They reek of bitter jealousy.
