I think he brought some good points up, but yes a promotion for his school and method.
I am still a relative beginner - but to me it does depend on your (or the MA or MMA you studying) goal. Most systems have some blend of goals. I always had a hard time knowing how to define the methods I study - Inosanto JKD/Kali. Is it mixed ? Yes I study boxing, MT, BJJ, boxing and we spar. Is it self defense ? Yes I study weapons and "dirty" tactics and street scenarios . Is it TMA ? Yes I study a bit of Wing Chun, Silat, Kali, etc. also my school is big on honor and respect and beavior.
Even the Gracie's (well Royce) acknowledge that BJJ is a blend or a blur - having its roots in street defense, but also being taught mainly now for competition.
I would also agree with OP that the sport of MMA has mostly degraded into honor less, crude, insulating, disrespectful brawls. Kind of a reflection of our society. It is a pleasure to occasionally see fighters like Holly Holm bring some class into the sport.
This is what I'm talking about. TMA is far more than just MMA plus a special uniform and some bowing and philosophy about respect and honor. Far more.
And while it's OK to not understand what TMA is about, it's not OK to define what it is if one doesn't actually know.
Example:
"I don't know much about karate (etc), but I know all about how it compares to MMA."
GRRR. No. Just no.
