So... Why did it take two years for them to remove the DLCs?

Now, don't get me wrong; I'm glad they finally did. I also wasn't ever particularly upset by it, and have thought for years that complaints about the DLC (at least to the extent that they became) were overblown.

That said, it feels really weird that they chose to delay that in-particular for so long. As far as I'm aware, there was no technical limitation in delisting them, and for items like Ferrystones, it seems convenient that they happened to be delisted only after the Eternal Ferrystone was added as a normal item anyway.

I'm not even alleging something nefarious here; I'm just really questioning how such a situation took place. I hope that in the future, Capcom will answer faster to such feedback that can be answered quickly--or prevent situations like that in the future outright.
