Chris primary motivations for drawing Sonichu and publishing it as a webcomic visible by everyone was to be renowned for his work, getting fame and praises, and advertizing himself as a component of his Love Quest to find a sweetheart from the ground-up. When none of it happenned, he saw no point to continue to draw his comics for the public as all he gets is criticism and mockery.
I don't entirely agree. If you look at the very first couple videos, he seems genuinely surprised that he has so many "fans". So I don't think he had massive fame on his radar to begin with.
Sonichu and CWCville were, and still are, an imaginary best friend and fantasy world for Chris. When things don't go his way in real life, he fixes them in CWCville by constructing a parallel universe which differs only by changing the things he doesn't like about the real world.
He did seem to want to share it with some people. He drew Sonichu stuff for the people around him, distributed the news-dash at PVCC, and threw some stuff up online. But I think he initially envisioned it as a way of interacting with people around him.
Then when Sonichu hit it big with trolls and Christorians, he dreamed much bigger. It is not hard to convince Chris to revise his opinions of himself upwards. So if he has a little bit of reinforcement telling him Sonichu is great, he is going to start believing it is the greatest thing ever and destined to become world famous.
But when publicizing Sonichu became more trouble than it was worth to him, he backed off. For reasons he didn't quite understand, but eventually realized were there, Sonichu drew the attention of trolls, led to parodies and enemies like ABL and Liquid, led to pressure to produce more, and didn't win him money, respect, or china. So he backed off.
But the headcanon kept going. Sonichu and CWCville pop into existence every time Chris wants to escape reality into his imagination a little. Sometimes he drew things or made lego models to make the fantasy world a little more real, but sometimes he just imagined the better world with an electric hedgehog sidekick. So Sonichu has gone with him on his journeys through the loss of his father, his gender identity issues, the housefire, the reunion/galpals issues, Catherine, etc. These are all part of Sonichu canon, in Chris mind. After all, all that Sonichu canon ever was was what came out of Chris imagination. Why is this any different?
Recently Chris started poking Sonichu's head out into the public eye a little bit, with the eBay merch. It has been fairly successful. And judging by the way he talked about it on the Catie date, a point of pride for him. People are willing to give him a fair bit of money for Sonichu stuff. But I think he is still a little bit wary about the stuff he went through last time. So he is exploring slowly, and figuring out what steps he is comfortable with. He is now aware of both the upsides and the downsides of Sonichu and the "fame" it brings him, and he is trying to work out, in his own muddled way, how to maximize the upside and minimize the downside.
