let me find and interview the renzo gracie did concerning the matter. He literally lost his shit over Royce's kids, rener and them, disrespecting one of his students talking about "the real jiu jitsu" and that the student probably should not train with them. He even accused them as trying to turn BJJ into Karate or Kung Fu where they start saying I could show you, but it might kill you.
Listen to rener now. He goes on and on about "real fight situation"...he is in 100% marketing mode and he does talk shit about just about everyone else now. So Renzo pretty much put them and Royce and even Helio on blast about "the real jiu jitsu". They are marketing "Gracie Combatives" as the ultimate in self-defense and in interviews are saying that if it's not gracie university jiu jitsu it's not "real jiu jitsu"
The interview is here...

"You know what happened, my friend: I see a lot of people now, especially my family, saying that. “Oh, I know the real jiu jitsu, you don’t know the real jiu jitsu.” We all learn from the same place, we all develop the same art together, growing up. But for some reason, once they jump in a plane and they move to America they try to sell a product, like the American people are a bunch of fools. Right now, I became American, and I know there are no fools here.
Do they pay for good service? They do. So if you feed them the real technique, if you give them the real sport, and everything like a good product, they will buy it and they don’t care about the price. But don’t try to bullshit them and expect them to accept anything you try to shove down their throat, because this is not the greatest country in the world for no reason. In reality, I see this crap today, “this is the real jiu jitsu”…let me be honest, I see jiu jitsu now turning into Krav Maga. Turn into kung fu! Like they are selling things that will chop your head in half, with a karate chop.
You know, its become a joke. Let me tell you what the real jiu jitsu is: the real jiu jitsu is the one that doesn’t back away from a challenge. It goes at the obstacle and defends its flag. It’s like, if you want to claim that you have the best fighting style, you should be in the UFC kicking some ass. That’s where the best competition is.
So when people call me, saying “this is the real jiu jitsu,” the next thing they are going to say is “I cannot use it, because I could kill you!” [laughs] You know, that’s what I heard my whole life, from those fake martial artists who claim they were better than everybody else. So believe it my friend, I live my whole life watching this and seeing this. We were always against that, and now suddenly one branch of my family is turning into that! It’s claiming that, but doesn’t go on the proving ground to prove it, does not step into the place where he should actually be representing jiu jitsu, to do it." - Renzo Gracie
Now Rener responded and apologized for any missunderstanding but STILL maintained that it was the real jiu jitsu, yada yada in that he thought that the defensive attacking from guard was the best system...he also said that he did not feel the need to prove the system saying that his camp would win some and Gracie Barra's camp would win some.
What I love about 10th planet is they put their shit on the mat. People may not like eddie...people may not like eddie belting folks no-gi...but they can't argue with the system.
