Amazing you made a good point.
If I sell a used Watchtower book or magazine on Ebay ... I am not violating any copyright. I own the material because I bought the material and can freely sell it. If anyone writes a book, and libels the Society, or violates rules governing fair use in copyright, then the Society has every right to sue the violator.
In my own opinion the WTS is just annoyed because they didn't think of it and people are making tons of money selling materials from the society. Like I was given 5 original slides from the Photo Drama and if I wanted to sell them they couldn't stop me as they were a gift to me and if I had to list it under something on ebay I would use like under category of photos ,postcards, tin plate pictures hand painted glass slides and how on earth are they going to know about it.??
So instead of calling it all WT stuff maybe choose a different tltle for selling those items.
And of course the Society would have to sue every used book store in the world as was mentioned that the watchtower literature is sold in most of these stores. I myself have bought items from the Society in used book stores and Good will and even the Salvation Army sells their books. and second hand stores. Boo woo , what will the WATCHTOWER DO?
It will be interesting to see what transpires.
