First......Huh? What are you trying to say, or ask? If you're making a comment about a breeder developing a strain that someone else was already selling, what's your point? Most of the popular strains are available from multiple breeders. Look at purp, lemon, northern lights, OG, diesel, etc.
If I'm wrong, and you're not trying to stir some sort of poo pot, I apologize, but your statement, question, just wasn't very coherent.
