Because Bethesda's games always require a shit ton of mods to be playable so they are basically charging extra for OTHER PEOPLE'S WORK just so people can actually have a decent game in addition to paying 60 dollars to even being able to mod it in the first place? Bethesda also has very little involvement in mod development, most of those people do that out of their free time, with no budget and just for passion, so for Bethesda to then claim they are entitled to receive money for that is preposterous.
