Bitcoin is not decentralized June 1, 2011
Bitcoin was designed by Satoshi Nakamoto, and the primary client is developed by a bunch of folks at bitcoin.org. Do you care who these people are? In theory, you shouldn’t: all they do is develop an open source client for an open source protocol. Anyone else can develop their own client (and some people have) and no one, save the agreement of everyone in the Bitcoin network, can change the protocol. This is because the Bitcoin network is designed to be decentralized.
