Exactly these parameters are the ones helping webmasters identify what the user wants. Knowing what pages are popular, where the users come from and what acquisition channels can you use and at what costs in order to bring eye-balls to your content influence directly what content area is going to be invested into and expanded by the content providers, which makes them do exactly what the user wants.

In a world without analytics you have tons of crappy content written or created at the whip of an executive who thinks she's good at guessing market demand (and nobody in the company can prove her wrong scientifically speaking before the job is done). That content will prove to be a failure when it's launched in let's say 9 out of 10 cases, which means 9 bankrupt projects, 10 times less interesting content on the web at 10 times higher costs of production, which in turn leads to less competition, higher prices (paywalls anyone?), reduced rate of learning/innovation etc.

I have a balanced view on the issue and I know the pros and cons of each side, including the privacy issues involved for everyone when surfing the web. But I'm sad when I see remarks as "I hope your product dies" or when someone chooses to blatantly represent just one side of the story.
