I can understand the bad feelings towards KOs, but I'm not so sure about the high-quality KOs of certain toys, such as the Dinobots. From what I've heard, their molds have been lost/damaged too much for repair, so an Encore release is not possible. So the options for people after them are originals, who may be missing bits and be in poor condition, and the aforementioned high-quality KOs.
So while it's annoying for collectors that these KOs are released, they can represent the only means of getting the toy in good condition for others.
If they don't care about Transformers, then why do they keep making them? Why are they trying to get Animated toys released despite the fact that the franchise is essentially over? That fact alone proves that they care about Transformers.
