It's weird that the comics industry doesn't view itself the way the music industry does.
Once music piracy hit big, there was really no putting the genie back in the bottle. Selling music was never going to be profitable again.
Services like Spotify did replace piracy for a whole lot of people, but no one is out there living comfortable off the money coming in off those kinds of services.
But musicians still make money, on things like touring and merch. The actual music doesn't have value as a thing to be sold anymore, but it has value in creating and keeping fans, so there's demand for touring and merch.
Comics are the same way, but the actual creators don't benefit from it. Just like music makes money from touring and merch, comics make money from movie adaptations, video games, and an endless amount of merch. But creators don't see that money if they're work-for-hire. They only see that money on comics they own, where they're the one making these deals.
But even from Marvel and DC's perspective, they don't treat comics like a loss leader the same way the music industry sees music. And comics totally should be a loss leader, with the only purpose bring to keep people interested in characters and stories so they buy more merch and all that. And to look at what resonates with people, as a test area to see which concepts are worth adapting into more profitable media.
