Did you just assume they are actively promoting it as if it has valid medicinal uses?

This article is actually helping to provide facts about the subject. You should be supportive of this article, not disparaging it.

The chopping technique is not really that necessary. It's great for chopping lots of veggies at speed, but if you're just cutting veggies for a single meal then there's not that much benefit unless you're already highly practiced and that's your default.
What's far more important is just being cognizant for each cut you make. Walk don't run.

If you want to spend the time and effort to practice that technique, go for it. But the benefits don't really make it worth it for most people.
The technique described in the image is not the only "good technique". A person could reasonably develop their own "good technique" simply by being cognizant of their cutting.
