While I feel the WT is under a curse for changing the good news, and that those who are responsible for what is written in these publications are twisting the Scriptures to their own destruction (if they don't repent).
I don't feel this curse and destruction will be seen by the demise of the WT.
I feel each one will be judged individually by God on judgement day and at that time will feel the curse and destruction.
But I do feel that the free flow of information on the internet will be very devastating for the WT and may eventually lead to complete demise. One can only hope.
I think also that people by means of the internet are getting strenght to fight the WT and this sharring of fellowship and information is still in its little snowball rolling down a mountain side stage, and in not too much time will reach the gigantic stage.
Ever straw is needed to break the camels back.
