In my personal opinion, whatever individual feelings about the nature of JW teachings and the danger posed about them, this type of activity by the authorities should be robustly condemned.
Fundamentally Jehovah's Witnesses do have the freedom to do what they do under Russian law yet the authorities insist on twisting the legal system and resorting to underhand tactics to try and put them in the same box as all the other undesirables identified by the corrupt leadership.
Bear in mind that the same methods are being used against homosexuals, transgender people, political dissidents, similar religions and other minorities to suppress free speech and free will.
The fact that this type of behaviour is sanctioned from the top down should be ringing alarm bells about how far Russia really has come in terms of embracing an open society.
Pushing these people underground has never stopped them. Years of persecution under the communist regime did nothing to prevent the spread of the creed. What is more, JWs love a good persecution story. It simply reinforces their faith. There is plenty of content in the literature that has been openly exposed to allow people to see what is really in there. In fact, if the Russian authorities would be far better helping translate some of the best sites (e.g. jwfacts) into Russian and tweaking their firewalls to point requests to jw.org to Russia language content that exposes the teachings for the bunch of junk they really are.
