Interesting and frightening compilation of facts. I also recommend interested people to read https://www.cambridge.org/ch/universitypress/subjects/econom....

Copyright would be something useful in principle if it actually enabled authors and composers to make a sufficient living. But this is not the case (a few years ago I analyzed the published data of SUISA and saw that as a composer you can only achieve a sufficient income with a probability of 0.1%; SUISA itself costed 50% more than was paid out to copyright holders; almost three times as much was paid out to publishers as to authors). Instead, copyright (as well as patent law) today primarily serves the corporations to enforce their oligopoly. And of course many lawyers earn a lot of money with it.
