Thanks, Petra!
The way I see it, it's fine for the Borg to receive and distribute these boxes, provided (1) they give them out on the basis of need, not religious affiliation, (2) they are not paid as an organization to do so and then expect the "brothers" to do the actual work at their own expense, and (3) they do not even HINT that the recipient should donate to the Borg because of this "gift."
I would bet dollars to donuts that none of the above three conditions are true of the JW distribution system. In my experience, they don't do anything without a financial angle of some kind.
