I could care less what you do or don't do in the privacy of your own home but when you start selling fish that effect everyone else that's where I have a problem. This is the perfect example of the butterfly effect which you sell your hyrbrids to someone who breeds and sells them or turns them into the local fish store, and someone purchases those fish unknowingly is how we have so many issues with certain genus of fish.
It's situations like this have wrecked a good number of genus, try to find a pure strain of Amphilophus citrinellus almost everything now is disgusting mix of amphilophus labiatus/citrinellus or midevil now is a better term. the next fish that is being effected is the Amphilophus trimaculatus, Vieja maculicauda and Vieja. bimaculatus being crossbred by so called hobbyist. I don't even need to comment on the swimming monstosity the flowerhorn or the blood parrot, these are fish that should be culled as well on a pure ethical point of view.
What you don't understand or if you do then need to rethink why you keep fish, but we are talking about tens of thousands of fish effecting generation after generation of fish and future fishkeepers. So for the brief time you decide to do this it will effect fish/people for years to come.
We have a obligation to fellow fishkeepers and a responsability to nature to ensure fish like this are culled in egg form, with ZERO oppurtunity to leave your home aquarium. Personally if your that selfish that you don't care about your fellow hobbyist then you have bigger issues you need to deal on a personal level and I feel sorry for you. That is not meant as a insult rather than some personal reflection of why you truly would consider a decision like this.
