It tastes nasty to you. That’s not something objective thing. You can dislike it all you want, but that doesn’t mean other people think the same.

And you can’t just say “all mold tastes nasty”, different kinds used in different ways have as wide of a spectrum of tastes as anything else. Common things that use mold: soy sauce, miso, tempeh, sake, cured meats, and many different kinds of cheeses (not just blue cheese) and more.
