@Rambone My theory is that :
Possibly, he probably ruffled too many feathers with his outspoken views and comments towards the big wigs in the industry. I think advertisers possibly were getting ticked off by his comments and possibly would have pulled money/funding?
Possibly, other industry powerhouses probably got sick of his preaching and needed to silence him? 
Possibly, he also may have refused to partake in possible nasty, deviant things behind the scenes? Possibly, sugar daddies do not like getting told no?
