Asperchu, Simonla and Billy Mays didn't upset him because Chris believes in that world. It's because Sonichu is basically his "happy place." It's a fictional world that he controls where everyone loves him, everything goes his way and no one can do things he doesn't like.
One of the things he hates about reality is that he can't control it - it's a chaotic place where there are no concrete rules and people can do whatever they like. That's not a problem in Sonichu. Everything happens exactly as he wants it to.
But then someone else comes in and messes around with his world, well, there goes his refuge. The logical thing to do would be to just say "that doesn't count," but Chris is a concrete thinker. Any change made, especially if it's one made by him (albeit through blackmail), did happen.
I guess one way to describe Chris' view of his world would be to imagine it as a painting or a model of something fictional. It's not real, but it has a definite form and can be damaged.
This is a difficult idea to grasp, seeing how Chris eventually included his real-life stressors into things, but it is extremely true. And if you want to verify it, you need to go through the history of Sonichu as a comic:
It's very interesting to me that he started actively drawing the comic when he was suspended from PVCC & turned down by Sarah Hammer, that's when life was meanest to him (at the time), thus he needed a hugbox, that was probably the point where the comic turned from an idea he entertains every once in a while to something he feels he has to do, you will notice that it is quite innocent and boring (very similar to today's incarnation, btw).
But Chris can't spend all day drawing the comics, he has a love quest to attend to!
So he makes those trips to malls and retail stores to find his sweetheart, and those end as we all know, and given that Chris is largely a confrontation-averse wimp, he naturally has things left unsaid, and it EATS at him (
think of George Costanza needing to retort to the shrimp joke). So he starts inserting those events into the comics, but with his side fully said as he wishes, and him being the victor in everything
*. This turns Sonichu into a hugbox + an explicit power fantasy comic.
Eventually, he gets discovered by trolls, and gets owned in every possible and impossible way, thus, his power fantasy starts including revenge fantasies on his tormentors & love fantasies with his imaginary sweethearts. One of their attack vectors is through his comics, they keep asking him tough questions about it, they keep criticizing its quality and content, and eventually, they come up with a character (Simonla), and after he
includes steals it, they demand that he kill it off.
After a lot of back & forth, he relents and kills off Simonla.
This seemingly affects him more than anything, he completely stops drawing the comics, he begins withdrawing from the online world, and he completely disappears.
Later he returns to making the comics, but this time, he brings it back to basics (sort of, because now Ponies are on his mind far more than Sonic), there is no
explicit power fantasy, but it is still a hugbox, and his circumstances now are much more dire than in the comic's beginnings, so it is now more of an
implicit power fantasy, he doesn't necessarily correct any real-life events, but the comic still depicts his OCs with what he feels he needs now (a rainbow-tinted life, filled with friends that always revere & appreciate him..etc), his latest OC (Night Star) has everything he's wishing for:
- Psychic Powers: So he can know what everybody's thinking and not necessarily have to think things through himself
- A Fantasy Childhood: In which he is more appreciated and acknowledged for his talents (lol).
This is the best I can summarize the comic's history, I'm pretty sure someone here will probably find something wrong in there.

* With that said, he never is the victor when it comes to his love quest, even in the comics, I think this is because he doesn't know what life in a relationship is really like, and thus has no reference point for it, he has references for imagining the wedding day, the hanky panky..etc. But he clearly never envisioned what life will be beyond that, and amazingly enough, never found anything in TV or Vidya either.
