The franchise business is a good business. I think this is really similar. You can go get a Big Mac, it will be consistent wherever you get it, very predictable. It ain't bad. Until you get a real burger from someone that knows what they are doing and gives an actual shit about making a good burger. Then you'll know the difference. If Rener and Ryron are the Ray Crock of bjj, they are literally creating McDojos.
I don't think we need to worry about watering down real bjj. It may take off and even get big, come to dominate the market. But nobody except an idiot (the world is full of them) will confuse a Big Mac with a real burger. It will probably help to get the douches out of the real academies.
