An anonymous reader writes: About two thirds of websites run Google code (mostly Analytics, AdSense, and +1) that tells Google what you do there and where you came from. (Also Analytics is used by 63% of Fortune 500 companies and 71% of the top 10k websites.) 800 million Android phones are in use (that's 11% of all humans), telling Google pretty much everywhere they go, everything they do, and everyone they talk to. Hundreds of millions of people use Google Maps. Over 400 million people use Gmail, telling Google everything they write and receive by email. Plus untold millions use Google Toolbar. Does Google do anything with this data? And even if they "don't be evil" with it today, is there anything stopping them from "being evil" with it tomorrow? What about 20 years from now when they are a second-rate company and some investment group buys out their assets? Do you block Google code in your browsing habits? Do you run Google code on your websites?
