Don’t be too hard on Youtube. The how-to videos people put out there are immensely valuable, have easily saved me thousands of dollars by teaching me how to do basic home repairs, changing the brakes and mufflers on my cars, etc.
Youtube can be downloaded instead of streamed and can bypass any restrictions that providers put on streaming. And your point is valid, how-to videos are useful. But I don’t think it is a very high percentage of the total.
