I have no issue with TMAs incorporating Bjj into their curriculums, but they should really give credit where credit is due. This particular school claims that these techniques come from one of their kata, and it's been translated for the modern day. In actuality, they're techniques that come from Bjj, and while I have some issue with how those techniques are presented (the stuff he's doing after losing the back mount is.... interesting. Like seriously, just hook your legs to avoid getting tossed off), the execution wasn't awful in general. I don't understand why such schools simply can't say that they went to a Bjj or MMA gym and learned ground fighting. Do they think that their methods would be looked down on if they incorporated a "sport" into their system? Again, I'm happy that they have chosen to teach their students ground fighting, I just don't understand why they need to hide where they're getting these techniques from.
