> A) amazon alone decides when to float credits and their price

Yes.

> B) authors are promised a certain rate (40%) of the price, but in reality this credit system destroys that %% completely

No. They are not promised a rate of the retail price. They are promised a share of the net sales of credits, proportional to how many of the credits were spent on their books. They should know the key parts of the business model here: Audible sell the credits for significantly cheaper than the retail price, and the narrators are being paid based on the actual amount spent on the credits not based on the retail price.

> C) in the end amazon makes always a >60% profit off each book, irrespective of the price sold.

No. The minimum revenue per-book guarantee is being hit every single month. So the narrators are being paid a bigger share than the contract promised, and Amazon is paying that difference from their cut.

> D) Their incentive is thus to sell as many units as they can,

And since the earlier points were incorrect, this conclusion doesn't actually follow.
