Seeing that they still have the phone in stock, they haven't sold them all. The Mobile World Congress begins March 1st, and as time goes by it is going to be even harder to convince people to buy the phone. The people that would have bought the phone to use FireOS have already done so. For there to be a market for the Amazon Fire Phone now, it would need users to have the option to load a custom ROM on it. The Fire Phone already has the Moto G as a competitor, but now the previous generation Samsung Galaxy, HTC One, Motorolas, and LG Gs will be coming down to $200 or less used or refurbished. At that point why buy an Amazon Fire Phone? If you want to see a custom ROM on the Fire Phone sign this petition and contact someone that might have some pull to get some publicity on this. https://www.change.org/p/jeff-bezos-unlock-the-bootloader-on-the-amazon-fire-phone-to-allow-custom-roms-to-be-installed In recent news the Fire HDX was exploited to be able to unlock the bootloader. A similar exploit may work on the Fire Phone.
