Simple. If that thing used electronic media to spread the message, then how would it be able to enslave the masses by forcing them to go door to door wasting all their time and money (not to mention, putting whatever carbon dioxide in the air wasting all that gas doing so) to spread it? Joke-hova simply wants people to not have either money or time, and that is a great way to waste both. Using electronic devices to spread the message would be too efficient, saving people's time and money.
And then, what happens when that thing pulls the whole Internet away from people (aside a few corporate "news" outlets)? No Internet, no means of getting this message to the masses--and with an Internet, there is the chance of people using it in ways the reptilians don't want (such as for freedom). Either way, these electronic devices would only be either useless (once the whole Internet is taken away) or counterproductive (if people start debunking the whole religion, and the whole bible to boot).
