Amazon can add or drop advertising partners on this page at any time, and you only find out by re-reading the list. This time a partner was removed, which is neutral or slightly good for you. But the same silent process could add partners later. Your saved cookie choices apply to whatever list is current.
What you can do — Recheck your cookie settings in Amazon's consent menu from time to time, and use the "Detalles" menu to see what each vendor says it does with your data.
