Ok, for clarification: Watchtower is politically neutral (it doesn't stand for or against any political force or agenda) and isn't a political organization, it's a religious one. In the same time, it's surely not "separate from the world" and sometimes, defending its interests, involved in activities that could be deemed political.
Also, your narrative (something like "the were warned but ignored everything") is distorted. The org wasn't taxed, only some properties were because they belonged to foreign entity. Unconstitutional anti-missionary law<*> was enacted in summer 2016; the anti-JW plan was adopted not later than in 2014. In 2014-2016, there were multiple cases with the same scenario: police conducts raids under false pretext (like "we suspect that the stolen furniture can be stored in KH" in Stavropol region); the banned literature is planted; the local organization is banned. I very closely followed those events, read hundreds of published documents and know what I'm talking about. Add ridiculous customs cases, add hate propaganda campaign.
As to the last statement, I doubt it's based on something other than prejudice. If the org was concerned only about property, why did and does it fight for Korean conscience objectors, Witnesses prosecuted in Kazakhstan, Kyrgyzstan, Azerbaijan etc. - and also in Russia?
<*> Also, you wrote that JWs were restricted like "every other religion". That's incorrect. The anti-missionary law was applied only against Protestants, Hare Krishna followers, Orthodox independent groups, some Muslims in non-Muslim regions and other religious minorities. The Russian Orthodox Church routinely and openly violates that law, but it wasn't applied against it.
