While I think his charging for pixelated images is too much! But, I think I know why he is really doing it!
As many of you, no doubt, follow his TikTok, you know he LOVES Japanese Anime! And in Japan the viewing of a person's "personal bits" isn't legal
Read this: According to Article 175 of the Japanese Penal Code, it is illegal to share "indecent materials." Though this may sound familiar to the rules closer to home, Japanese artistes of the adult variety have found a way to circumvent this: They simply blur out the genitalia.
So I think it has more to do with affinity towards Japanese culture than his own "shyness."
