If this issue wasn't sexual in nature wouldn't you think doc or someone would release a statement to cut down on the rumors. If it's not assault related all this speculation can be damning either way.

It probably is related to that, but I am guessing the secrecy is probably because Twitch knew and didn't act/covered it up. And now no one is saying anything because everyone involved would come out looking worse; thus they all probably just wants it to go away...

Twitch would look like total shitclowns if they put out a statement condemning behavior they themselves enabled. And if he is guilty, nothing he could say would help, it would only make it worse.

The third parties who claim to be in the know like this guy and that former Twitch employee who tweeted earlier are probably keeping their mouths shut for the sake of the victim(s), because if they wanted it out in the open they would could have/would have put it out there on their own.

This is all baseless conjecture though. But it doesn't doesn't seem like it could be anything else. If it were criminal (with authorities involved), one would think there would be records AND no one would have any reason to keep their mouths shut about it... And if it were contract/business related, it might make sense if just Twitch dropped him and everything was radio silent on that front alone, but various companies are doing it, which makes one think its a lot bigger than that.
