The question isn't whether In-Q-Tel supports the CIA. It's whether Facebook was funded by In-Q-Tel, and even the article that Wikipedia uses as a citation doesn't seem too sure how strong of a connection there is:
> The second round of funding into Facebook ($US12.7 million) came from venture capital firm Accel Partners. Its manager James Breyer was formerly chairman of the National Venture Capital Association, and served on the board with Gilman Louie, CEO of In-Q-Tel, a venture capital firm established by the Central Intelligence Agency in 1999. One of the company's key areas of expertise are in "data mining technologies".
