I agree with you that the internet is a probably viewed as a major thorn in the side of the JWs. I am surprised that the Watchtower hasn't put out some articles saying avoid the internet etc. (please feel free to correct if they have....I am not in the loop on current doctrinal changes but then given how frequently they change them, I don't know who would be up to date).
One thing I have noticed about the JWs over the last 20 years is that they do move forward in certain customs i.e. music and fashion they just seem to keep things 20 years behind the times. For example back in the 80s they were okay with certain Pop music from the 50s and even 60s and certain fasions of even the 70s but if you asked an older "brother" or "sister" they would tell you these styles while accepted now were considered inspired by Satan in their time. Much is the same now. I see JWs dressing in apparel that back in the 80s would have been considered inappropriate. I see them wearing more makeup than they would have been permitted in the 80s and I see some listening to music that 15 years ago was not approved of.
So while this internet age will certainly enlighten JWs about what the "truth" really is all about, I still see them making lifestyle adjustments necessary to keep some new converts coming into the fold. The thing is their adjustments always seem to be in a delayed way probably to keep the JWs feeling different (and sometimes ackward) with the world around them.
To me this is interesting because I see this as more of a threat to the grey haired ones. Surely it must be confusing or even annoying that the JWs would brand Satanic a certain mode of lifestyle only for it to be accepted 20 years later. On the one hand they say not to mix with the world and on the other hand they say to it's okay to try and blend in. It surely must show the Organization for what it is.
