I have enough of a model of people to understand why there's pushback but at the same time the leap from "asking for something" to "asking something for everyone" doesn't seem like a big one.

I also find it confusing how people can use clips from movies, songs etc. not in the public domain or use public domain works outright but not see how contributing to the commons benefits society.

I appreciate your comment but my feeling is that a closer understanding is that the overton window is such that fair use, public domain and old work enriching the commons are so taken for granted that people have forgotten how important they are.
