Explain the difference between GB/IBJJF & GJJ

I thought Royler, Rickson, Royce, ?, ? have nothing to do with Rorion and in fact have had some legal/family squabbles over the family name. I always thought it was Rorion against the rest of his siblings over the rights to the name.

Royce and Rorion are in it together as far as I know. That may have changed in recent years though.

I was referring to the statements from the Helio sons who claim to teach true JJ. nothing to do with copyright.
 
Does anyone know the high level deltas between the curriculums of Royler, Royce, Rickson, Relson and Rorion.
 

Maybe it has something to do with Chuck Norris?
