Why do so many people hate the Gracie Family?

I believe it has more to do with the different styles of fighting. For a long time jujitsu fighters dominated MMA, which the Gracie family contributed greatly to. Then along came the strikers that wanted to prove that their style was more dominate. There are still few fighters that are extremely proficient in both and I emphasize the word few. This continues to be a debate in gyms and training everywhere. I personally don't understand why fighters don't see it neccesary to work on better escapes.
