I guess they'd argue that the people in China don't count, because people in China don't get to choose Google. But yeah, the stats they use from "StatCounter" are clearly not representative for what the world uses.
Choice/Free will is an arbitrary line in the sand, one could argue how much choice we have about consuming google search when it is "85-90"% monopolistic business with well documented anti-competitive practices.
Chinese consumers perhaps have more choice than we do, Baidu is only about 60% market share. They do get to choose, it more that Google is not one of the options available to them, it is not like if not Baidu then it is a Phone Book.
