Sambo doesn't has chokes though,
This kind of arrogance is why people in America think BJJ are elitists, BJJ is a martial art, its a set of principles and philosophy based on certain techniques.
The correct thing would simply say "Grappling won this fight" because the triangle choke its not exclusive of BJJ, its used a lot more in judo newaza because its a technique which works fast and its clearly seen as working by a ref and therefore there it has a lot of success rate compared to other chokes who may be stopped early.
BJJ did not invented grappling, neither does the Japanese, grappling has existed in all cultures at some point, some to more development than others, the perception that BJJ developed alone its also wrong, the gracies were enthusiasts of cross-training and they did fought judokas and wrestlers from Brazil from which they learned too. However, in the end its all about the individual, not the techniques.
The reason its simple, Americans simply didn't liked grappling before the UFC, they were oblivious to the fact that over 1 century ago in carnivals, they had grapplers doing locks, chokes and throws.
Things like saying that Judo or Sambo has no guard (Fedor armbars anyone), no positional grappling etc etc.
To make it short
1.- This is grappling, the actual art its probably Judo or Sambo because of the location, the techniques are not exclusive to any art, they usually have centuries of existing and have been reinvented many times, If Newton and Leibniz came up independently with differential calculus, its not hard to imagine two guys getting at the same conclusion of something much simpler.
2.- MAs are not entirely a technique a jab can be boxing, karate, kung fu, judo, muay thai, BJJ, kickboxing etc etc, its the philosophy, the mentality and the strategy what defines an art.
3.- This guy is obviously a rookie, his sankaku (Which is japanese for triangle) jime (which is japanese for choke) sucks.
