Perhaps this is

or maybe even a little naive of me, but despite how he seemingly dodged so many controversies I get the feeling Harmon's gonna hit a wall eventually.
Comparing Harmon's work history to his current project lineup, I can't help but notice he's gone from internet and TV shorts, to writing offers on film productions like Kung Fu Panda (which from the sounds of his MySpace, he was let go from for being unable to meet a deadline considering how many blog posts he wrote about procrastinating on writing it) to producing television. But since then, he's slowly going backwards where outside the occasional executive producer credit for an indie film, most of his work now is on Rick and Morty (where animation is still the short bus of television productions) and his web shows.
While it might not seem like he's facing repercussions now, it seems like he's definitely burned some bridges that probably aren't going to be open to him again any time soon, and at the rate he's going he'll very likely end up more or less back where he started content wise. So there probably won't be any huge backlash towards Harmon so much that he'll be gradually phased out the more he proves to be a liability until he's eventually just left sitting on his podcast going "I used to write for television you know."
