That claim of environmental impact is just incorrect when it comes to the junk content.
The bad ones are barely watched; sitting on a hard drive after getting transcoded isn't an environmental disaster.
You could try to argue that popular culture is fundamentally bad; people have been saying that about TV when I was a kid, dance music before that, novels in the 1800s, Christmas in Puritan New England, and the Olympics in ancient Rome.
The people tend to disagree.
