I think if you think that is the takeaway here you are falling for a narrative spun by who as far as I can tell has been a bad-faith actor for at least 5 years if not more.

A guy who-

-openly admits in his blog post to wanting the careers of people he's mentioning destroyed

-talks about people attempting to work with him in (cautious) good faith as "love bombing" and comparing them to domestic abusers

-denies all responsibility for posting stuff as inflammatory as this by finishing it off with a "teehee don't harass anyone wink wink"

-had to be asked multiple times not to make an antisemitic joke in the post or repeatedly call hussie a man while exclusively he/him-ing em and only made the minor changes of dropping the "ish" off the end of the still antisemitic joke and find/replacing all instances of calling hussie a man and he/him-ing her with "person" and "they/them"

-made a separate article attempting to convince his audience that you basically couldn't trust anyone with a license to make homestuck content unless they started agreeing with him

-insists in his big post about how the evil abusive sexually dominating man homestuck creator is bullying homestuck fans that the actual terms of what hussie and/or the HICU wanted him to do are irrelevant and the reader doesn't need to know them

is just maybe not a reliable narrator, and if any parts of his blog are to be trusted on this it would be the html transcripts that while dubiously authentic don't seem to be disputed yet, and don't even come close to supporting the "hussie is taking down homestuck fanworks and he's coming for YOURS next" story being spun. Maybe in the coming days evidence will come out that what happened here really was bullying using legal action against gio's version of the uhc, but at the moment that is very much not a clear conclusion, and it just kind of reads like a deal falling through and legal action being taken because one party wasn't willing to play ball.

The issue poeple are taking with the tone of his blog post is not that gio is a "drama queen", the issue they are taking is gio having a clear agenda of driving more people he dislikes off of homestuck by pushing this story and trying to poison people's view of a new fanworks collective and forum for discussion right as they're starting up by convincing them he is the only trustworthy source on homestuck and is speaking truth to power.
