Re: This doesn't make sense.
Well it does,
What you're refering to is privacy, not security. Individuals offer FB this data up. The tricky bit is when an individual not only offers their own personal data up but also those of their peers.
The product FB sells is the data and the advertising space, the service it provides is a personal data collection tool offered for free which many consumers want to participate in. FB have a massive interest in keeping people's data secure as that is their product which they sell in various forms.
* Please note this post isn't about the pro's and cons of FB's business model. Thats a whole other kettle of fish.
