I'm not sure I understand your post here, sleepydragon,
What kind of conflict of interest are your referring to here? If I remember correctly [I may not], Mr. Buffett gave an interview at an Allen session/gathering, where he talked about that he considered WFC a better bank than JPM, but he had bought 1 million shares in JPM personally. [Needless to say, that I have since been puzzled about that statement.] I don't have the actual link.
