I think the whole thing is suspect, in that some things might be "technically true" but presented out of context or with twisted intentions in part because of the real premise of these blog posts:

Andrew Hussie tried to work with Gio (someone who AH didn't trust for what are probably behind-the-scenes valid reasons) in supporting a project that is entirely based on essentially bootlegging the comic that AH made. With stipulations. Which is why I think there's so much effort put into making AH seem like a dictator over the rest of FRAF/HICU, who apparently didn't have issues with AH's "demands." One of those stipulations of confidentiality being based on Gio's I think obvious history of presenting AH and Homestuck as a poisoned project (Sarah Z avoiding talking to any HS members and just getting gossip and speculation from Gio). Gio kept dragging his feet and wanting to be able to do whatever he wanted with it. And decided that he needed to get ahead of whatever fallout of burning bridges with the actual owner of the work he was trying to control access over. Thus, presenting this whole thing as AH forcing Gio to ~KILL HOMESTUCK!!!~. As if Homestuck doesn't exist on all of our hard drives at this point anyways.

He wants people to panic and be mad at AH for something HE is doing.

Like if I made a comic and someone was basically republishing it while I was reworking a deal with my main publisher, I think I would be in a pretty similar mood as AH. Lowkey this could only happen in the HS fandom because AH has tried for years to let people do what they want, which seems to keep exploding. So I'm really not surprised nor resentful of AH trying to create a code of conduct.
