I wouldn't be shocked if it was all true. When I was in college in Atlanta, I was a party and became friends with someone who works at adultswim. This was right after season 2 ended, mid 2016, and I was trying to find out when the expected date of season 3 was. She didn't want to tell me anything b/c of NDAs, but eventually liquid courage got her to spill the beans. I was told he was a piece of sh*t who came into work 2 hours later than everyone else drunk and high, never completed any assignments, never picked up his phone, didn't treat any employees with respect, and was on such a high horse he thought he was above everyone. She said the reason I can't tell you when season 3 is coming out is due to the fact not a single person at adultswim knew anything about his plans, not even the execs. She claimed the work environment ever since he came was terrible and that her stress grew tremendously. Granted I believe she worked in ads and would only get a few days to design something due to how late roiland was in submitting stuff, so she is a little biased.
