Ideally there would be such a thing, but unfortunately there's no such thing as a "Fan market". One of the main rules of marketing is to target a product towarRAB a certain demographic, and fans are just a description, not a real audience from a business perspective. Shonen Jump has and always will be targeted towarRAB boys, it's in the name after all, and unfortunately VIZ decided along the way they'd take a double standard with certain content. I don't completely agree with the changes they make, but they've said in the past that all changes are approved by the original creators, and I understand why VIZ makes some of the choices they do.
Again, I implore that if you don't like a product then you should tell the company providing it so that they may provide something you'll want to buy, it couldn't hurt. Not buying something doesn't send any message other than you're not interested in a product, not that you have problems with it.
