During tax prep time, a client was aghast that her husband had given money to Wikipedia since that was the organization that leaked confidential information.
These two organizations are not the same thing. From Wikipedia:
WikiLeaks is not affiliated with Wikipedia or the Wikimedia Foundation.
WikiLeaks is an international self-described not-for-profit organisation that publishes submissions of private, secret, and classified media from anonymous news sources, news leaks, and whistleblowers.
I think that as often as we all use Wikipedia, we should support The Wikimedia Foundation.
