Not to mention that no one is forcing anyone to use their custom morphs, it's just an option in their products, a kind of bonus if you will, for those that do.

And in the case of Justice, I'd say the detail, texture size, and amount of parts meant that AS had to go "bare-bones" with morphs to keep the file size from being too big. And as their tutorial mentions, you can easily use the V4 Morph Magnet Kit at DAZ for any V4 morphs you may want to use.
I've seen several products from other merchants, nowhere near  as high quality as any AS stuff, that didn't come with any morphs, not even posing-assistance ones, and those merchants appear to be making enough off their products to warrant making more.
