Users everywhere have had to put up with U.S law for a long time. The laws and norms of the USA are more or less "fully baked in". Try posting a nipple or copyrighted track, for example. If Facebook had come from a different place, all songs and body bits might be Ok but perhaps discussion of government would be banned. I can't tell if that would actually be a better facebook than the one we got.
Nipples do reflect American sensibilities although it is understandable that many companies do not want to go down that road as it could lead to becoming distributors of porn. I think you will find that many countries outside of Europe agree or don't think that these rules go far enough.
