I think it's a bad thing by itself. With the wikipedia example - anyone can edit, editors can by anonymous or psuedonomous, and there is no preference, implicit or explicit, for race and gender. Over the years wikipedia has been built up, by volunteers, into an amazing and valuable resource. Now, the organization controlling their work and this global good, decides that aggregate race and gender statistics are a problem. Wikipedia is a little too white, and a little too male, and that's a bad thing! Imagine applying this reason to any other organization and any other race and gender combination. Here's a crazy idea - if you want to reduce race and gender based prejudice, start by not having clear race and gender prejudices yourself.
