Could possibly be, then again satellite TV was in use decades before the internet was as widespread and used as today. Older tech is all that would be needed for the world to see the 2 witnesses. JMHOWe know that the current technology will continue to function long enough for the two witnesses to do their thing and then be killed.
The bible says their bodies will be seen by everyone around the world. So, maybe it lasts until mid-trib, when the antichrist stands in the temple and declares himself to be God. Once he does that, perhaps he will have something else set up and ready to go............ for, perhaps he will use
this same technology............. Don't really know, but needn't think about it that much. We'll be gone by then.
