PBA:
I do not think ZD is saying that all technology ought to be banned. Rather, I think his intent is to argue the following:
There are several problems associated with the internet ie. harmful websites etc. There are those who would therefore have the internet banned because of these issues.
However, these issues exist in a plethora of other technological advances. Ie. if you are going to talk to a member of the opposite gender online, you can just as easily get in your car and drive to a place where you can talk to a member of the opposite gender. Why not ban driving?
If internet can be the cause of Bittul Torah and should therefore be banned, then the ban should also include such technologies such as cars, cell phones, digital cameras which also can tempt individuals to commit other aveiras.
To not ban other such “problems” would be inconsistent with the reasoning behind the banning of the internet.
