He had been charged for commiting domestic abuse and so he was let go from a bunch of shows including Rick and Morty. The charges were later dropped but it's unclear whether his reputation will recover, especially since some other people accused him of toxic behavior like telling someone to go into sexual slavery.
...Which is pretty much par for the course for a lot of sexual assault cases as well. RAINN reports that, out of every 1000 sexual assaults, 310 get reported to police, 50 result in arrests, and only 28 result in convictions. So the DA dropping the case before even going to trial isn't all that surprising. It doesn't mean that he isn't guilty, just that the DA didn't think they were going to be able to prove it in court.
I had an GF that was raped and she immediately went to the police office and had a rape kit done and all that. The DA refused to prosecute because “he’d probably just say it was consensual and we don’t have evidence otherwise without a confession”
It’s a shitty situation because the law legitimately should not be throwing people in prison simply on the word of the accuser. “Beyond a reasonable doubt” is an important aspect of the justice system.
On the other hand, it does result in many rapists getting away with their crimes.
