I wish they'd make more of a distinction between pre- and post-exercise stretching. As I understand it, pre-exercise stretching really is pretty useless if not outright harmful. That's what the article seems to focus on, but it's maddeningly vague. OTOH, I haven't heard such a severe indictment of post-exercise stretching. It's what I do. I run more than 95% of other runners who enter 1000 km/year challenges that enable me to make such comparisons, and that's already a pretty self-selected group. I've had one serious encounter with plantar fasciitis, lesser incidents of ankle or knee tenderness, and occasionally some mild shin splints. I feel like some simple stretches - nothing aggressive or elaborate - after each run have helped with some of these. Perhaps stretching really is over-hyped, but this article seems just as questionable on the other side.
