I bet half of adsense users don't even know they are signed in to Google by just checking their account.
So how do they think Google knows who they are?
They probably think that leaving the site logs them out (it should, but doesn't).
So how do they think Google knows who they are when they go back to the site?
I cannot think of a single site that logs users out on leaving a page. They mostly either require a logout button or time out after inactivity.
Amazon never times you out and does not label the logout link clearly.
Why is every focusing on Google, and ignoring the everyone else that does it, and why is Apple not getting any blame? Google also deserve some credit for fixing the browser issue that allows this.
I will continue to use Firefox with Cookie Whitelist, which means I have very few cookies set. I login to Google from a separate browser, usually on a different IP.
