keywords: "And if [getting sports implemented] is the problem"
I never said not to do sports (neither did the article: it merely pointed out that telling people to "_just_ do sports" may not be helpful) and I never tried to sell a silver bullet.
This is unlike the inevitable influx of comments in the style of "ignore therapy, just imitate my sports routine, and if you can't, just try harder". Those appear under _every_ depression-related submission on hacker news.
Those comments are harmful: therapy already comes with stigma, so it's not the obvious route - unlike, as you can see here, sports. Everybody proposes sports, healthy eating habits and regular sleep (btw: what about the depressed who can easily sleep 20 hours a day, should they just get one more nap?).
Reinforcing the stigma around therapy discourages folks from taking a route that might help them.
The "just try harder" angle that's all too often seen in such comments is also harmful: What do you think did those people do (often for years) before they consciously consider that something might be wrong with them? Exactly: they buckled up and tried harder - and they will continue until they crack unless something changes fundamentally.
