PDF archive of Hero Factory's doc (it was too big to attach):

I would think whatever attorney he's consulting would be advising him not to post such a document. I also think it would be better if he left out the "I've been losing money on this thing btw" part at the beginning but not having seen the stream he's replying to, maybe I'm missing context.
An indie "Eldritch Space Pirate Lewdtuber/ASMRtist/Villain/Memelord" named Adonis Thuul QRTed the Hero Factory tweet and dropped his own doc about maltreatment at Twitchcon:

The PDF for that one was small enough to attach. tldr is that Adonis was supposed to be a "promoter" for HF but was instead treated as a servant, made to carry bags and fetch water and the like. Definitely on the tame side of the scale of Twitchcon horror stories but if true it speaks of River being a bit of a prima donna.
An indie named Corvo Apollo ("Streamer, Writer, Editor, Goofball (He/Him)") also QRTed the post with this bit of mockery:

I don't feel like I know all that much about the situation yet and certainly can't say if anyone is really right or wrong but from what I've seen so far, the CEO and the talents all seem like young people who are trying to handle Professional Business Professionally but going about it rather poorly.
