This is what Spotify was from the beginning. It was always going to be exploitative, it was always going to turn to the dark side and embrace the every form of enshittification possible because it was born that way.
It was born out of sleight of hand between broadcast and retail.
It was born out of papering over the economics of piracy with a thin veener of false legitimacy, where the word decimated doesn't begin to cover what actually happened to artist payouts because it's off by more than an order of magnitude. The shameless scale of it would make Walmart blush.
It was born out of collecting consumers with convenience and a dash of zeitgeist.
It was born screwing the people who create the work the platform depends on and passing the savings on to you.
Screwing with you was inevitable, it was just put off until later.
