Google is an advertising company which you can avoid if you wish.

My local grocery offers discounts to those who use an identification card. The card is free but if I use it to get the discounts it does allow them to capture my purchases. Is it evil? I would argue no. Like any buying decision, it is my choice. I can pay extra for privacy or give up privacy for the discounts.

With Google, I can avoid them for privacy or give up privacy for convenience. It's still my choice.

Maemo.org knows every time I log in, what forums I visit, which threads I read and which I respond to, and it can tie it all to my email account. Is this evil as well?
