I understand the rationale, but it's not without cost.
If I've taken the time to do an in-person (or even a lengthy set of calls), then there really has to be something in it for me after they decline, or I won't apply with them again.
Also, if everything else seems like a match, my potential new mates and I hit it off, and they clearly need to fill the position, the vacuum left by a lack of explanation with the decline often leaves me wondering whether it didn't involve irrelevant (and often illegal) demographic bias. No way to really know, of course, but like everyone else, I play the probabilities.
