How to feel about the ethics of the spider wobble?

[RiA MaU]

I won't have any part in it, personally. I view it the same way as breeding a dog with bad hips.

Understandable, but at the same time, a spider wobble is also not as harmful to the animal than said hip issues (according to everything I've read about it). I can see not breeding something dangerous, but I don't feel it's quite the same.
