I made this point in another post: the take-away from this link shouldn't be how bad it was of Facebook to not realise that making available powerful search tools for already-public data might put some people in an unfortunate spotlight. The real take-away is that we shouldn't live in a world where people should be scared to be openly gay in Iran, or openly a Falun Gong member in China. Those are the things we should focus on and try and change. And we should appreciate, rather than chastise, the tools which make us realise that there are things we need to improve in the world.
