There's a difference between doing something harmful to yourself repeatedly for shits and giggles, and at your own discretion, and voluntarily following something through to its conclusion when somebody else plans the exercise for you. Perhaps the subtle distinction is only in my own head, but I do believe there is one.
The dude doesn't deserve a pat on the back for the meditation itself. If he had been fasting, following a running/swimming program, studying go/baduk life-and-death problems, or playing guitar exercises for 10 days, and he stuck with it to the end and documented it similarly, I feel he would still deserve kudos. Giving one's undivided attention to a new and uncomfortable activity, 10 hours a day for 10 days, is a challenge for most people.
Hell, I'm lucky if I can give up coffee or power drinks for 10 straight days. The 2 or three times I completed a 24-hour fast, I felt some sense of accomplishment. And keeping up with some kind of exercise routine? Forget about it.
And that's why I found his story so layered and interesting. It's not just about the meditation (which was interesting in its own right), but about his dedication, and his privilege, and his turning his mind's eye inward.
Berate him (or me) if you will. You said it best: to each their own.
