That's my point. The discussion is about instructors mashing on the inflator buttons of students.I talk about it in class (dry land) and demonstrate it on myself in shallow water, e.g., show what a full wing of air will do and also how to unhook and re -attache an inflator hose. At no point do I hammer an inflator button on any of my students at any time. However, I do have them unhook and re-attache the hose many times at depth while they are neutrally buoyant as a skill familiarization.
I hope that clears up the rec portion of the discussion.
Talking about it/demonstrating it is very different that doing it to students.
So what the OP is discussing is never performed in any recreational courses.
