Ultrafundamentalist control freakism. Just admit that you hate all sources of information that aren't you. You claim that it's about reading, but you also want to restrict what people can read. Then if peope really read the Bible, you still complain if it's not your favorite version and not using your cult's own interpretative literature. Because someone might actually learn things in it that you don't like, or discover contradictions, or study the development of the compilation, put the verses in their proper context. Oh noes!
A more valid concern is that with digital services, they now know precisely what you're listening to and when. It was more difficult to do that kind of survey with analog broadcast and it wasn't instant live data.
Another potential concern is the equipment, its capabilities and vulnerabilities, what corporations do with the data they provide, etc. For instance, some of that equipment can listen and record you today. The same with your mobile devices, that can additionally track your displacements.
But most importantly, do you sleep with your beard outside or inside the covers?? You could also avoid the distraction of web spamming in favor of more Bible reading yourself, no?
