Guy is a purple belt in the gi. I seriously doubt that he doesn't realize that heel hooks in the gi are only allowed at a very few schools. Also TS said the guy has trained at that school before, so again he probably knee the rules.
Highlighted for emphasis.
Maybe I've just trained at too many places, but I've used my speech the past 6 years after a guy put me in a neck crank and I was off the mat for a few months.
I know a lot of leg lock guys get pissy about any thread that complains about a leg lock or getting hurt by a leg lock, but this thread is more about an asshole than about leg locks.
Nice generalization there. Likewise, I could generalize that all BJJ guys get pissy when they get leg locked. There's really no need for these kind of sweeping assumptions, I think we can both agree?
And yes it was a cheap tap, because it was an illegal technique. Using an illegal technique to get a tap is cheap.
Again, dude, there's only illegal technique if there are rules. If you didn't lay down ground rules with the guy, how the eff do you expect him to know what is "illegal"?
With heel hooks in the gi, i think thats one thing you should always check to see if its ok first when rolling with someone you've never met before, especially since its illegal in the gi. People are going to assume if its illegal, people won't do it. You wouldn't grab someones clothes and try to bow and arrow someone with their t shirt and afterwards say "my bad, I'm a gi guy and my specialty is lapel chokes. I've been choked out with my t shirt a bunch of times, you just got fight your way through it. Thats all I can tell you".
Is that a bad example?
I don't necessarily think your example is fitting for a vast number of reasons.
Third, he does not have enough control to roll safely. If he did, he would not have cranked that heel hook even though he caught it. A good leg lock guy will not cause injury to his partner in training. He will know what he has and just be safe with it. This guy was not safe.
This right here is the real issue. The guy obviously has no control over himself to roll effectively and safely. Everyone's making a big shit that he used a heel hook, but I'm upset that the guy saw the need to crank it. The guy used a move you weren't expecting. Big deal. It's like if a guy threw on a neck crank; you'd just tap, start over, and say politely, "Hey man, I'm not so hip on those, can we not use them?"
The real issue is that the guy just exploded into the move and cranked you. It's the equivolent of throwing an armbar on faster than a guy can tap, or exploding into a shoulder lock. Obviously a lot of ego, and isn't the type of person you would want to roll with. If you can't safely control a submission, or privately say to yourself "I know I had it" and let go, you aren't the type of person I want to train with.
On a side note, I sincerely hope all of you "HEEL HOOKS ARE ILLEEEGALL!!1!" types never compete in ADCC/GQ/NAGA. You will be in for a very rude awakening.
