People forget Anderson Silva shouted words to the effect of "Where's your Jiu Jitsu now, playboy?" to Demian Maia in their title fight.

This spoke to the big economic class divide in Brazil. BJJ particularly Gracie Jiu Jitsu has always had a gentrification problem.

The rift between Helio Gracie & Oswaldo Fadda is fascinating history study.

Fadda wanted to teach Jiu Jitsu to poorer classes in Brazil while Gracie was a snob. BJJ's long aversion to leg locks came from Helio's resentment to Fadda's poorer students beating his wealthy ones.

Even then, a Jiu Jitsu Gi / Kimono was a relatively expensive uniform in Brazil a century ago. Luta Livre (a descendant of Catch Wrestling in Brazil) could be taught without the Gi, so the appeal to those who lived in the Favelas (slums) was clear.

The BJJ vs Luta Livre rivalry was a class war, one ultimately LL wasn't victorious in. Jiu Jitsu did become more affordable in Brazil over the years, many Lutadors were able to become Jiu-Jitsueiros, but BJJ was able to gentrify internationally after the success of UFC.

Holes in BJJ have been filled over the years by adoption (or appropriation) from other grappling arts, but a new tactic became common in ensuring BJJ supremacy: misinformation.

When lies and half-truths about other arts' efficacy stopped working, claims of injury prevailed.

I've honestly lost count over the years of stories I've heard levied at known places like CSW or Hayastan, or lesser-known Catch Wrestling and Sambo gyms that they were dangerous and that you'd get hurt going there.

These stories were invariably perpetuated by Jiu-Jitsu schools.

As little as 10 years ago this misinformation was spread at the height of "Leglock Paranoia". Today you'll find many BJJ gyms trying to find the edge in having the most effective leglock game - while phrasing it as a Jiu-Jitsu evolution, and not cross-training assimilation.

Information surprisingly not spread about by many Jiu-Jitsu schools: arts like Judo, Wrestling & Sambo are generally much more affordable to train in.

Jiu Jitsu has become today's capitalist & corporatist grappling art.
