If this is true, I hope Google has the sense to sue:

unverified sources (i.e. rumors) said that chinese search engine
Baidu.com set up a special task force to search politically sensitive
terms in Google.com, therefore making Google unstable or even totally
inaccessable to chinese users, it’s said that baidu even wrote to the
government against Google’s "politically harmful contents" in china.

Baidu is seeking a Nasdaq or overseas listing.
