of course not - they are called average users for a reason. But when shit hits the fan and someone's privacy was violated and made the media, then FB will have a nightmare of a PR incident, and if there is money involved, probably law suits etc. Its just human nature to ignore what you can - and this privacy problem is a long term problem that tends to get ignored in the short term.
You are somehow assuming that they only had a reason to learn from their last mistake. The fact that there have been numerous mistakes suggests that they don't get it and won't learn from it.
