Twitch probably doesn't care beyond reputational damage/liability.
a settled lawsuit between Twitch and Beahm, where neither party admitted to any wrongdoing, and his contract was paid.
In fact it sounds like Twitch made an effort to keep it quiet, which was successful until these former employees spoke out (hope they don't suffer consequences)
Edit to add: Which is not to say there couldn't be separate consequences. It's just not going to come from Twitch. I'm sure a certain three letter agency is quite a bit more interested in Beahm now.
