There's a real, specific concern here that doesn't apply to Google analytics on blogs. The concern is that if this data is available for purchase by a company consumers haven't heard of, it's available for purchase by police. Police could use location details to track, arrest, or harass people they don't like. And this has implications outside the U.S. as well. But also I think you'll find that some of the same people in this thread also complain about Google analytics. My personal website, for example, does not use Google analytics.
