Among other reasons, the WTBTS needed to become an NGO with the UN in order to bring their message and get established abroad with a sort of 'protection'; the end definitely justified the means in this case.
It can be rationalized with the biblical passage which states that Christians can use 'the world' in order to advance the preaching of the word everywhere, or to use "unjust riches" for the work of the Lord, being "cunning as snakes but innocent like doves", or some such quotes found in the NT.
This goes on with many a Company/Corporation/Religious Org/etc. originating in the USA and wanting to gain acceptance abroad. Common practice, really.
Well now... I sure woke up with the JW personality prevalent today. Call it whatever, it's call "survival". Get over it already.
