The former lead dev (who is still part of the team) seems to think many people are out to get him for no good reason. He has claimed repeatedly that Calyx devs have sent harassers to target him for years (from spamming gore or nazi content in the matrix channels, to swatting him and almost getting him killed by the police) and that they constantly speak ill of him, but has never actually shown any proof. Instead, he sources his own past claims about how he has shown proof, in a sort of endless loop.

Also, youtuber Techlore made a 5 second joke about GOS's extreme approach to security in his mostly positive review of it, which the lead Dev took as a personal attack. After which he started attributing harassment to him too. He made a later video talking about it, and Louis Rossman commented on it expressing concern. After which, the lead Dev accused him to being complicit in the harassment.

Eventually he stepped down as project manager, citing how the harassment and bullying he constantly got was too much. But to my knowledge no one has actually seen it ever.
