Yes, which is why I don't use Google Chrome. I know that they get my information in other ways, but I try to make it difficult for them in whatever way I can. Google will one day know everything about everyone, and hackers and/or the government will get their dirty mitts on that info sooner or later.
Are you concerned about Google collecting your personal and browsing data?
No, because Google doesn't (and won't ever) care about the actual fact I go to Belly's Store, or that I'm a geek and not a girly pink person. The data they gather is too big to get their eyes on a single person. They use this data for 2 reasons: surveys (for instance: trafic, popularity on YouTube,..) and targeted advertisment. They use this for their services and nothing else, and they wouldn't win anything using the data with a toxic purpose. Some would say some hackers could use them baddly, but again they would use the date a whole, not for ONE person (except if they're against someone they know). And also, I think (in fact I know) that hackers could easily the same intel in other ways than Google. I think that people against this data gathering are a bit paranoid and they don't have a real clue about Google motivations (don't get offended please, I don't mean to offend, I'm just explaining my opinion).
