The nature of bullshido policing changed after 10-15 years of MMA
I remember in mid-00's TKD we were still happily denying reality and saying MMA was dumb meathead stuff that was beneath us, so the Martial Arts Reformation took a long time to trickle down after 1993.
But after say 15 years it was clear which martial arts available in the West worked and which didn't. Like there was no need to do a dojo storm on a karate dojo to figure out if they could fight, you knew they couldn't (
these JBG-approved karate guys aside). So they just got ignored and the bullshido policing focused on dojo storming fake BJJ black belts or whatever.
Places like China maybe didn't get affected by this quite as much, so some CMA bullshido lived on until people like
Xu Xiaodong started lighting up tai chi masters on camera. Maybe people had already started ignoring it like in the West, but there were still people like Xu who cared enough to expose it publicly.
The point is that if your style was outside BJJ/judo/wrestling/boxing/MT/kyokushin, the bullshido police just didn't bother with it after a certain point, as MMA had exposed what actually worked. So obscure (for Westerners) Filipino styles just didn't really appear on the radar for your average Bullshido beat cop like it would have if it was widely available in 1993.
e.g. if you saw an ad for a 9th Dan Grandmaster teaching you the dim mak for $50 a session in 2024, you wouldn't get angry because it's bullshit, you'd just ignore it. But I get the feeling during the 90s and early 00s there were still a lot of people actively trying to expose that stuff because it wasn't as well-known to be BS as it is now, so these guys were getting respect despite not having any fighting ability.
tl;dr it doesn't get exposed because these days people just assume its bullshit and go on with their day (not to say that it
is bullshit or not, just that that's the default assumption, people just won't get invested in it)
