Google Buzz and Economic Surveillance

I find interesting about the NY Times article and the reactions of some users to Google Buzz that they primarily stress the danger that China, Iran, etc could use Buzz for engaging in the (political) surveillance of political oppositionists and that they label such endeavaours totalitarian, while at the same time they do not provide a critique of the economic surveillance machine constituted by Google’s expanding services, its collection, storage, analysis, and commodification of personal data, and its market dominance.
