[cypher]

If you think about the numbers they breed even if they were to suddenly become conscientious about the problems with breeding hybrids I doubt very much they would be able to source enough pure WW or Campbell's & the start up cost of a new breeding programme with two new species would probably be very high too.
I would imagine the majority of people buying hybrids don't even realise exactly what they are & the people selling them must be making a comfortable profit with no reason (by their way of thinking!) to change anything.
I'm not sure but I imagine that hybridisation originally began out of ignorance & or accident & they have just carried on breeding with the stock they have.
I don't like to think what would happen to the hybrids if they did have a change of heart either tbh!
