The question is not whether what the WTS did is right or wrong in itself but rather it's the hypocrisy of their action, should a ... R&F JW merely attends the church service of another religion s/he will be expelled.
I don't see the hypocrisy of which you speak. The WTS was an NGO for strategic reasons. I can't imagine a JW having stragetic reasons as a basis for attending a church service of another religion. A JW would have to attend such a church service for strategic reasons in order for there be a true comparison between what the person did and the WTS becoming an NGO. .
