Is the founder of FB protestant, or maybe the leadership? Does vkontakte, a foreign company, in a country with no protestant culture offer less restrictive naming policies?

Characterizing the issue as one caused (and the inference is only protestant Anglo culture would cause) this kind of names requirement is disconnected from reality. Companies in non Anglo and non protestant places have similar and even more restrictive policies. And also this idea of names is not an Anglo concept, as it was characterized.
