This approach in Russia sounds extreme but it did not come unexpected. There are laws in a country, rightly or wrongly, but these laws are to be obeyed. The WT had the idea they could get away with their own approach or otherwise change course of things. It did not work. This would be for any organisation, religious or not.
Some or probably most JWs will see this as a fulfilment of some WT prophecy. A few might wake up. Nevertheless, I have seen political parties being dissolved because their resources dried up, people lost interest etc. In other words, if more countries adopt a similar policy, it can have a big impact.
