I know both sides of this debate. While all the breeders (except one) that I met were great, responsible people who cared about their snakes, I also know that some are not. My uncle, for example, bought about 20 burmese pythons about 15 years ago. He wanted to start a snake breeding business because it would make him loads of money. The snakes died within a week (All 20). The guy actually turned out to be a sociopath in the end, so that might have played into it.
People like that DO exist, but luckily they are few and far between. BPs are great animals, and no matter what people do with them they should remember that.
