To someone with the proper technical skills, it's trivial as you say. But until you do something like what these guys have done, it's dishonest (or geek-myopic) to say that it was trivially available before. When you package it up like this to inject into a receptive media channel, you make it "available" to an audience that would not have had access to this information before. The rhetorical impact of choosing "playing hooky" over "weight" is obvious, and not the problem here. The problem is that someone whose main motivation was obviously geek cred and not solving a problem went straight for a collateral-damage campaign instead of one of the many other options available. Fixing the Facebook privacy policy is not worth endangering the livelihood of even one of these people.
