whenever i see someone try to criticise worldbuilding as a practice, most are actually criticising the current and relatively recent trend of spinning off new works from existing already-popular fictional worlds championed by the disney/marvel blob, which is not so much worldbuilding as it is a cynical and risk-averse business plan specifically tailored to the current economic moment. the rest are usually reacting to the people above; having been convinced that worldbuilding is bad by someone gesturing at disney+ and saying "that's what worldbuilding is", they then find a way to redefine the term to exclude the things they like ("Dark Souls doesnt have worldbuilding, it has lore")
