Im a little surprised this is being brought up so long afterwards. yes it was obviously an intentional DoS, in my opinion.
also, while you were trying to be conservative with the number of witnesses writing letters, you may have forgotten that they were encouraged to write a letter to each of 5 or 6 ( something like that) officials, so your numbers may be wildly underestimated.
If you want to talk conspiracy theory, consider this: thanks to the efforts of the GB, the Russian gov now has names and addresses of potentially millions of JWs in and outside of Russia.
Yeah because bringing an important national public service to a crawl is not extremist in any way. May have been the nail in the coffin (that and their lies) of their case there but maybe that was the point. Framing trouble by decree, like so many other times.
