I wouldn't go as far as to say he's a bad guy and not to do business with him. The article in question was about how to run a snake business so it only makes sense that it would have some money tips in it and if your snake business is whats putting food on your family's table than who is to blame them for thinking about money?

The reason from what I can see os because you spend more money on a nice male that can be bred to more than one female. Females cost more so you can get a nice double gene male and a couple single gene females and not hurt your wallet as much =P
