If you think of a employee of a company violating a non-disclosure agreement and getting fired over it, then that's pretty much what happened to Darksydephil. That and acting like a complete asshole towards everybody, and threatening to sue YouTube and Google probably didn't help things.
Oh yeah, I'll just drop a video a detractor made compiling a few of the vlogs DSP made about this right here.
At first, DSP was like "oh I love Machinima they go to bat for me whenever I have any trouble", then he throws Machinima under the bus.
