He didn't want them to disclose his identity, because he didn't want his patients to see his name blasted out in major media as that could potentially impact their care.

You can think it's unreasonable, because if you are trying to connect SSC to an IRL name you could find it, and that's fine. I don't, because I think Alexander should've been given the exact same deference NYT offers others.
