@channel7 I don't disagree as much as I see some contradiction in:
You make the argument that the issue is exhausted athletes unable to control the eccentric motion. The exact same thing can happen to sHSPU. If you're barely touching the mat during the strict HSPUs you're still fresh and strong. As you get closer to fatigue, and the strict movement demands much more muscle resistance than the kipping, you're bound to become slower and slower while stringing reps along. And that invariably means resting on your head.
I find 1) also somewhat disingenuous because using proper form one should always be bracing their core and having active shoulders, even during the recovery of a kipping HSPU. If someone is relaxing in the bottom of the kipping this person will do exactly the same as fatigue sets in during a set of strict HSPU.
In regards to 3)
I suppose you don't program high rep deadlifts and any form of barbell/dumbbell squats or presses in your workouts? This caracterization of the strict HSPU as a "slow strength" movement is completely arbitrary and isn't really bound by any "scientific definition" is it? Are strict pullups also a slow strength movement? A "slow strength" exercise is one close to your max effort. If you can only do 2 strict handpushups, they'll be slow. If you can do 30 they'll be fast. The same applies to literally every strength exercise ever. HSPUs aren't different in any regard. Other possible application of "slow strength" movements is hypertrophy, by adding tempo to the equation. But this isn't mandatory, one can perform deadlifts/squats/presses/HSPUs as fast as possible or controlling the tempo, there's no one right way.
Safely based on what? The evidence you provide is anecdotal, and while it makes sense there's no exhaustive research being made to detect what exactly is wrong with kipping HSPUs, if there's something wrong with it. This is an opinion piece, well grounded in some aspects, I admit, but still an opinion piece nonetheless.
There are personal trainers who say deadlifts are dangerous and on first sight they indeed look dangerous. What's the counter argument for them? Research.
- Being a Crossfit coach since 2013 and advocating against kipping;
- Advocating exclusively against kipping in the HSPU.

Additionally the case has been made to me in the past that the intensity of the workout or WOD must remain high in order for it to be effective. I disagree with this too because while intensity is important and necessary, moving safely should be paramount.
