I don't exactly how this would work, but I am certain the Society would love to be a sole source internet service provider to all Kingdom Halls, Assembly Halls, etc. If they could do so, they would then offer the same to individual households. They would couch this as a way to protect the brothers from apostate sites and internet pornography, since these would be conveniently blocked by the loving brothers administering the ISP. Gotta protect the family from accidentally encountering such filth, ya know...
Over time, other undesirable sites could be blocked as well. The brothers must be shielded from atheist sites, web pages that advocate higher education, or those pesky unauthorized JW social media sites where individuals might engage in unmonitored conversations that could lead to independent thinking or (gasp!) criticizing the Governing Body and its ever-changing policies and interpretations.
It would also allow the Society to monitor which sites individuals visit, how often, and when. That's the only way to help the brothers avoid wasting time on frivolous entertainment or disloyal research from worldly sources.
You heard it here first, folks! Kingdom Internet Services, coming soon to cult compound near you.
