I have no idea what Brad Cherniak is on about here. I can't think of three more closed companies than Apple, Google, and the Wikimedia Foundation. They may give off the appearances of being "open", but I defy anyone to get a non-Apple MP3 player to play a song from the Apple iTunes store, and I defy anyone to get Google to disclose the evidence that led to an AdSense account being blocked, and I defy anyone to get the Wikimedia Foundation's executive director to disclose how much was paid to Q2 Consulting for research that was awarded without any competitive bid earlier this year. -- Gregory Kohs
