I quit AOPA about 5 years ago in disgust at their being in the pocket of the regulator. After 25 years being a member, i wrote them a letter explaining my view. I got no reply, no argument regarding my points, nada, nothing. Heck they could have talked me into staying if they had tried.
If they had made my letter and email public I would have been slightly pissed off. That they have made the resignation of another member public makes me glad I am not a part of them. I guess no attempt was made to get the said member to change his mind either.
