If I'm a product manager, and I cut a feature based on inaccurate analytics and lose paying customers because of it, blaming the customers ain't going to bring back the money I was making off them.

Chrome's analytics ought to say nobody uses Incognito Mode, but they'd be dumb to remove it.

I don't usually get to pick and choose what I share when you run analytics. For example, I might be fine with telling you that I saw a certain article on Hacker News; I however might not be OK with you seeing all the articles I click on.

But the vote is secret. Analytics is not.
