StoryFair Audiobooks launches a better, fairer way to to buy audiobooks. On StoryFair, authors now receive the highest royalty anywhere.
They frame it as though it's for user content, more likely it's to train AI, but in fact it gives them the right to do almost anything they want - up to (but not including) stealing the content outright.
I hope not! I hope they interpret it this way and are willing and able to take action, by removing their catalog or maybe even a class action lawsuit. 
Except Spotify is one of the only hopes against Audible. Audible gives terrible deals to authors, if you sell your audiobook exclusively through audible they take a 60% cut of the sale, and if you sell through multiple audiobook stores they take 75%.
And that's just the official numbers, according to this source they actually pay out even less than that. The average author's cut for an exclusive title is only 21%, and for a non-audible exclusive is only 13%.
Large established authors get significantly better deals, but all the smaller authors desperately need audiobook rivals like spotify to be a viable alternative to Audible's monopoly death grip on the industry. So it's not as simple as "boycott spotify", spotify or someone else badly needs to succeed in getting a meaningful slice of the market.
