Do they?

If it's all about the money, my guess would be Facebook has lost out on ad revenue, because a lot of the ad payers don't have customers.

There's still a third possibility, they're making some moral decision, although that's hard for me to believe given the company's past decisions. Maybe the lost revenue has made them make a moral decision?

It could always be a combination of these reasons, and I'm sure there's others I haven't accounted for.
