>The difference here is that presumably fewer record companies have the money to fund the development of their own streaming service.
They don't need it. With Apple Music, Google Play and Spotify majors can afford to destroy Spotify with royalties as they please, and users will just migrate to other platforms and continue to pay.
It's kinda funny once you think about it. Back in early 00's, when Napster appeared, everybody was "dude, record labels are dead, new business models, bla-bla-bla".
And now we are 18 years later, and majors are quite fine. And they did literally nothing for 18 years. No investments, no development, nothing. They just milked different internet services with their royalties.
