I see what you mean, I do have a slightly different take on it though, if I may. Yes the internet means information is freely available to those who want to research and people will wake up and leave or not get baptised etc because of doing so.
But, I also think that the dotborg website will be the mothership that will take WT into the future (at least they probably intend it to be). There are internet religions that do very very nicely for themselves. WT's business advisors would be stupid not to have figured this out. Either way sheer speculation and time will tell.
