Fine with me, but even Bill W. is not a leader. The principles are what keeps AA in business and without anonymity it would have failed years ago, IMHO, particularly with Bill W's massive ego.
And for what it's worth, Bill publicly broke his anonymity at his death, I have an original NYT with his death announced. Which further goes to it being to protect the alcoholic from his own ego. It was never a "secret" who Bill was, his full name was on many corporate documents that anyone could get from the NY state corporation commission, etc. And Bill never made his name a secret, he also referred to many others by their last names, particularly Hank Parkhurst, Fitz Mayo, and Jim Burwell and he referred to Dr. Bob as "Smitty."
