Google back down, and Baidu COO/CTO out.

No official news from Google yet, but it seems Google is back down to stay in China. Certainly the 2 biggest search engines in China recently stir a whole lot of stuffs recently. Now Baidu CTO and COO are all out for "personal reason". If in a conspiracy world, the rumor said that insiders from Google stole the source code, and maybe sold to some interested parties?
