You're just embarrassing yourself at this point, if you think that's full contact and not point scoring you clearly don't know what you're watching "bro".
First of all in that video they're wearing the typical point-scoring mittens. They're also pulling back their punches, the guy throwing a kick at 1.35 literally pulls it back before it lands so as to not make contact, at 2.06 they're exchanging punches which touch but they're trying not to make hard contact then one of them is literally shouting kiai's when he throws his punches, lol. The rest of the video is much of the same with guys touching for points and avoiding hard contact apart from that guy landing a knee (which doesn't even look to the head) and the other guy going down. Those are not full contact fights, they're continuous semi-contact point-scoring kumite, if you think otherwise let's stop the conversation here because you don't even know what you're watching.
You said "Been in goju for 20 years and the entirety of the goju kai organization which is one of the two largest organizations for goju does that kind of sparring and competition." So of course worded like that one would think those 20 years were spent in Goju Kai, either way you said "the entirety of the goju kai organization does that kind of sparring and competition", now you're saying it's not the entirety because you just don't know and you just can't find a single piece of footage to back it up. That video with "kudo-esque rules" as you call it is from Goju Ryu in Russia but I don't see anything about Goju Kai on it.
How often people train IS relevant because if you train 2-3 sessions a week but most of those sessions is spent on other stuff like kihon, kata, 1-step kumite and so on well guess what those who spend the entirety of their training sessions on actual fight training (like in KB, MT or boxing as you mention them) with full-contact sparring they will simply be better fighters quicker, that's quite obvious. So going back to what I said again, kata is a waste of time for someone whose goals is fighting.
Anyway it seems that we're going in circles and you're obviously changing your stance and what you say constantly and you can't even tell the difference between a semi-contact point scoring tournament and a full contact one. Great that you enjoy Karate but from all your threads and posts I get the vibe that you're trying to convince yourself that Karate is great and you're making the right choice by sticking to it. It also looks like you're trying really hard to convince others of the same thing.
