They liked the "background noise". They'd read with it on, have conversations shouting over it, and so on. Baffled me. I often wondered, why not just plop down a food blender and leave it on?
Why pay for cable?!
Mindless scrolling is the modern version of this, but it's worse because there isn't even a shared experience that might spur a conversation.
People like you and me are quite the opposite: we hate external structure and long to be left to our own thoughts and devices. It's not too dissimilar to micromanagement in that respect. What's the point of having a brain (and the rest of the body, that matter) if you can't use it?
