I agree failure is a failure but not that it's bad. Failure is neither good nor bad by itself. I think it's important to learn that a failure is not a reason to hate yourself - which is what usually feeds the depression. It's not constructive to dwell on the failure. It's necessary in fact to find out what the learning is and then see what strategies exist to minimize harm. That's not glorifying it in anyway. Falling down, for example, is not a beautiful thing but it's imperative to learn to get up - otherwise, what's the alternative? The article seem to make the claim that setbacks train your mind to accept failure as part of the process and not treat it any differently. What's wrong in that? There's no need to be a contrarian in everything.
