bethesda taught us a very important lesson a while ago - if your game isn’t good, then the modders won’t bother. Skyrim despite its flaws is a good game, and has mods to show it, Starfield despite its budget is pretty bad, and after the initial hype most ambitious mod projects were cancelled.

because of that i don’t think there’s any neferious plot behind the game makers celebrating their modding community, and the modding community certainly isn’t getting forced to work without pay - they’re passionate about the game and want to make something of their own within it, and honestly that builds a good portfolio for future use too
