Bethesda is a company so naturally they’re going to want to try and profit off of mods. But outside of the compatibility hiccups this doesn’t really sound that bad. It’s a nice way for modders to get paid for their work, it’s optional and it’ll hopefully make modding more accessible in general. The bigger concerns (to me) would be how badly are Bethesda ripping off modders, and whether it would fracture any communities, for instance if it was too difficult to make an ‘official’ mod as well as a traditional one, leading to modders abandoning one or the other. So long as Bethesda handle it well it could be fine.
