Well, banning transfusions and many other normal things is stupid and yet they do it! Why not banning the Internet at one stage or...like they do with the blood now...banning "whole" Internet use, but allowing fractions like jw.org or watchtowr.org? Normally one would expect that an organization's doctrine to evolve parallel with scientific discoveries. But in the case of the JW it was not always like that. There's always the danger of the "increasing light" which may become "new light" at any point and one kosher-today issue becomes not-kosher issue tommorrow. This is a paranoid cult, unpredictable and dangerous.
Of course the Borg will not be able to monitor and control what an average r&f is doing at home with his computer. But I suppose they could try to insert in his mind a stronger sense of guilt for using the net, you know, educate his "Christian-educated counscience".
