>For me the line is clear - illegal content must be removed, legal content must be left undisturbed, and if Facebook considers law of some country to run counter to their conscience, do not operate in that market.

The only problem is, since the internet is free and open, whether Facebook operates as a legal entity in a particular country or not, doesn't prevent internet users from that country to access the services. And Facebook doesn't have any obligations to ban IP ranges from that country. So, it's the country's responsibility to ban traffic to Facebook.
