but it appears that Sony had more restrictions still, and Bethesda decided that it had become unworkable. Mod support on Xbox One is already a different beast from the anything-goes frontier on PC - no copyrighted material, no nudity, no child murdering, limited file size, etc.
To read between the lines a little, it sounds like Sony was in support of mods on a theoretical level, but that the console manufacturer had too many restrictions for Bethesda to feel like it would be providing true mod support.
