Google provides many products and services that I use and like. I've never once had a Google ad which had something like "buy these window drapes, they go great with that new couch you bought last week". In fact, I've clicked on a few Google ads over the years (and ZERO other ads) simply because the product in the ad actually moderately interested me. As for the information "chrome passes to Google", well, that's no more information than they get from simply from tracking the links someone clicks in a Google search. I've never once been wronged by Google, or had them deleteriously affect my life. I don't see any harm in them knowing I frequent slashdot, xkcd, wikipedia, and click on many science and tech news articles throughout the day. I don't see any harm in them knowing I use their search engine to troubleshoot computer issues all day at work. If they use that information to serve me small, unobtrusive ads based on that information, and use said revenue to pay for stuff like Docs and Gmail, that's fine with me. I'd rather have them track my browsing habits, and have targeted ads than pay money for those services. It's not like some person is sitting around at google actively watching your every click, laughing, and choosing what ads to send you, it's all machines, and with hundreds of millions a day, they literally don't have time to put a human in front of that data, and never will.
