Which part of "Facebook doesn't require you to make your data public to target ads to you." are you disagreeing with?

I didn't disagree with that statement. I'm just explaining why Facebook wants users to "share" more data.

What is your explanation for why facebook removed the ability to make your profile picture private to non-friends?

Here is Facebook's explanation: http://www.facebook.com/privacy/explanation.php#basicinfo

Basically, if your profile picture were private, it would be hard for someone (who is your friend/acquaintance in real life) who isn't friends with you (on Facebook) already to find you on the site.
