Lots of digital ink has been spilled on this topic which I think has done a good job of exploring in various ways why it's probably not worth the time spent dwelling on it. Your average person just isn't that concerned with a creative team and their antics, even when there's a lot of drama and sore feelings involved. Even Gio and his most ardent supporters struggle to form a coherent, defensible case out of interpretations of law and ancient fanmerch takedowns. Why?

Because Gio, who self-describes in his socials as the guy who "saved homestuck" on a website copyrighted under his own name (or rather, not his name, but his online moniker.) is behaving incredibly anti-socially and any reasonably well-adjusted adult can tell that right away, even if they don't understand exactly why.

To speculate a bit, it seems to me Gio, and that whole reddit community as a whole, are all mired in some kind of parasocial animosity toward Homestuck's creators, and have been for years. It's deeply unhealthy behavior. I can't help but note the subreddit describes itself as the "largest, most active Homestuck community" which should tell you where their heads are at over there. Not fandom, mind, since a lot of them have nothing but derision for much of the content and the people responsible for it in their eyes. These are people who spent a significant portion of their lives online defining themselves as a massive anti-fandom, so it's only natural a resurgence of official content from the creators they've aligned themselves against for so long would lead to this kind of fallout. It's sad really, but little more than the consequences of their own decisions.

At the end of the day, however much you find criticisms of official Homestuck team behavior to be valid and worth discussion, however much interpersonal drama goes around the internet and Gio and these guys spinning their wheels and crying and yelling into the void, the fandom overall isn't going to get behind it and most folks wouldn't engage with it at all unless and until polite discourse breaks down into full-on cyberbullying. That's the good, healthy response to all this I think, and hopefully the last word I feel inclined to share.

Oh also this is kinda apropos of nothing, but he manufactured a cherub chess set and is gauging interest for a marketable product on one of his websites, all with no mention of Homestuck or a certain creator. All designed by Gio himself! Pretty impressive, huh?
