That's what they're doing: spending their time. They choose to do it by watching some kind of Internet content.

They can do it by watching ads or spending money. A lot of people hate spending money. Some don't have the money to spare; some just don't want the hassle of connecting a money source.

It helps that we got trained by television, where for many decades there was no paid alternative. We accepted advertising as the only way to watch General Hospital or Star Trek or whatever.

We'd probably all be better off if we decided to watch fewer moving pictures and did something that didn't require ad support. But if people are going to just watch their entertainment, they're going to pay for it one way or the other.
