Here's one way the society uses inactives to fudge numbers to their advantage. This was posted regarding Germany in this thread: http://www.jehovahs-witness.com/forum/thread.asp?id=10964&site=3
All publishers had to sign the Publisher Card before which is now viewed as a proof of membership by the Religious Community. The number of 192'000 members is officially given unless there are only about 165'000 publishers. Because a corporation of public law has to have a minimum size also inactive members are counted.
I'm not aware of any similar advantage to the WT doing this in Canada, but like you, I'd be pretty pissed off to know that I still benefit the bastards in any way.
