The fact that something is useful doesn't automagically make it ethical. I'm sure aggregated GA provides a lot of useful information. Our point is that if you are using GA - for any reason - then you're a spy that prioritizes your addiction to analytics over the privacy the people visiting your site.

Unfortunately, given you're posts in this thread, I don't expect you to understand this. Upton Sinclair was very insightful when he said, "It is difficult to get a man to understand something, when his salary depends upon his not understanding it!".

Have fun inspecting your analytics reports and using that data for another round of page tweaking and tuning; it maybe be more socially acceptable than the Twitter user who continually refreshes their latest post to watch their hit rate increase, but still a sign of addiction.
