I don't think I have ever read so much rubbish in all my life. The whole article is full of half truths.
The society are against further education. They do isolate people for disagreeing with their policies. Everything is not out in the open when you start to study. There is not freedom to do whatever you like in employment. There is constant pressure to do more in service. Over the years thousands have died by following witness mandates i e no vaccinations, no transplants, national service and all their changes in the blood doctrine. They are totally adament something is right until it is proved otherwise.
Decision making is controlled by Brooklyn not somebody local. If a congregation regularly does not send enough contributions they will not get supplied the books or mags they want. If they do not agree with the society on something they are told to wait on Jehovah. They do not tell you that you may be right. Reading some outside material is definately frowned on. Anything that goes against the leaders ideas are a big no no.
And the best one is they don't consider themselves special. This is a complete lie. They are constantly taught that salvation only comes by association with this org.
If this guy is not a witness then he simply has accepted what he has been told by them.
