You're right, there is no problem with privacy. At least, for me & you. That's because we know that our facebook data went from private to public a long time ago, and we have modified our behaviour accordingly. However, you should also therefore know that not everyone in our social network understands the implications of these default changes. So, the geeks are upset on behalf of the non-geeks they know and love. And they should be. If you don't think so, I challenge you to question 5 of your less techie friends and family on this issue. You will be amazed at how few of them (a) understand what the hell you're on about, and (b) care.
