I don't know about that. Seems to me that the one major requirement is that you need to actually be in the right, and Apple needs to be in the wrong. If you run to the press for some perceived slight that nobody else cares about, you'll get roasted no matter how popular you are. If you got legitimately screwed by Apple, you'll generally get results even if nobody knew about you before. (Everybody loves an underdog story, after all.) I'm sure these factors can swing it for marginal cases, but, well, don't do it for marginal cases.
