The Velvet Rope: Turned away from Club RSS?

Christian Crumlish has a post this week saying that Dave Winer, who is moderating a Yahoo Group on RSS users, denied his request to join. If this is accurate, it seems odd to me that someone who is one of the loudest voices championing open source code and shared standards would not admit someone like Xian to the list. On the other hand, like so many tech related glitches, it may be that this is an error, or there is some other great and understandable reason that the Yahoo Customer Care denial for membership message just doesn’t address.
UPDATE: Dave wrote to say I misstated his position on open source code–he’s absolutely right, I did. See Scripting News for some good statements of Dave’s philosophy.
