It's not a matter of being "too good" for something. Herny got an actual job in the industry, and he has limited free time now. He had to choose what he'd rather work on in his leisure time; the same thing he's done for years, or a passion project that he's WANTED to do for years?
You don't have to like it. That's normal; you followed his work for the lewds, and now he doesn't do them nearly as often. I understand. That doesn't mean he's making a personal jab at you or others who feel like you, he's just changing course, and you have options for how you'll react to the change. If continuing to follow his work is out of the question, then you can just stop following him, stop giving him money if you currently do or ever did. But dragging him through the mud because he doesn't do what you want anymore is hilariously petty and shows you just want to wank to his lewds.
