That's slightly different because hacker culture creates a public commons that practitioners can use to make money. It is not clear to what extent this actually happens.

Perhaps EDM works like how hacker culture works. I just don't know much about that . But for more traditional musicians it seems harder to... monetize the work. But this was probably always true - it was not uncommon for touring musicians in the radio era before TV to take on sponsors. The span in which people were sustained mainly by record sales was pretty brief.
