That's not ironic. People have very different expectations between Gmail and Facebook. When I used FB I expect that my news feed is public to my friends. It's used for open social interaction. The same goes for Twitter. When I use Gmail I expect my emails and contacts to be private. I don't expect strangers to see what I'm doing. The user's experience and expectations are different. This is why Facebook has more leeway (but they still get * if they do something that opens up your profile to the public).
