Comparision of Facebook and Google privacy

I'm trying to find a comment someone made on HN within the last two months. It was a hyphenated list comparing how bad Google and Facebook are with user privacy. Facebook came out way worse.

I've searched HN a lot myself but haven't found the comment. Can anyone find it? My friends don't understand why I don't use these services and it'll be easier just to send them the list as an explanation.
