The Watchtower's website is just a feature of their campaign to misinform the public, serving to show the "world" that they are not against new technologies. Besides, they never come right out and tell their members to stay off the Internet any more than they came right out and said the end would come in 1975. They just give "encouragement" that the "spiritually strong" dutifully follow, protecting themselves from the dangers of the Internet.
Their website was never meant for the r/f, anyway. It's for those yet in spiritual darkness.
