Amazon originally paid out 70% like most other digital goods purveyors. Once they cornered the market they arbitrarily pushed it down to 25% (you only get 40% if you agree not to sell anywhere else). This means that for many authors, especially indie authors, they lose money publishing the audio version of their book.
I will also ack that I'm all for better legislation to help creators in a lot of this. I just don't know that this all is as clean a picture as you are making it. For an easy example, did audible drop their payout from 70 down to 20ish at the same time they dropped the average price that they sold at? That would change the story more than a little bit, if so. Do they also cover some of the upfront costs of production for some audio books?
JAQing off in defense of a monopolist is a bad look.
That said, please educate me on where I'm giving a clear lack of understanding on how it works. I'm basically seeing a couple big name authors that are effectively telling me I'm a bad person for buying audio books from Audible. But, far as I can see, every alternative is complete utter shite. Except the library, from which I still gladly get audio books on CD.
And again, there is no evidence that audible is lessoning consumer choice? There is some evidence that they lesson producer practical choice. But even that is weak? With few exceptions, mostly audible produced works, I can find all of the books I care about elsewhere.
You can call that whatever you want, but it sounds a lot like the descent to pre-Internet situations that weren't markers of stable quality and that many people who survived the 1980s don't want to see again.
They have 90% of the audio book market, likely. They do not have exclusives on that much, though. I'd hazard that 90% of the available book market is through the major publishers, still. At large, this makes sense, as most books are still written with upfront payments from publishers.
I would also not really shed much of a tear for Audible. I just don't understand the idea that getting rid of them moves us further from the old style. Seems more likely that the publishers would brow beat any future entry into the market so that it was much closer to how things were in the 80s and 90s.
