It wouldn't bother me if they were trying to create a breed with a purpose other than scamming people and making money, but today that's just what mutt breeders are doing.
I am a fan of the Catahoula Bulldog, which started out almost 100 years ago as a cross between a Catahoula Leopard Dog and an American Bulldog. There was, however, a reason they crossed them. People wanted a dog with the drive and intellegence of a Catahoula and the strength of a catch dog to bring the ferral hog home. Up until then they had to use two dogs. It generally worked and now the Catahoula Bulldog has been an established breed for over 50 years.

(American Bulldogs vary greatly in type, I'm not sure which lines were used in creating the Catahoula Bulldogs.)
I guess I'm trying to say I don't mind if someone sets out to create a breed for a purpose, and stops if it's not working the way they intended, like the Australian Guide Dog Society did when they found out their labradoodles weren't working. What gets me is when people cross breeds with the intent of making money, or creating a cute new name.
