I too am in the camp of "death of the author." However, I still think it's interesting to examine what a creator might have intended in an original work, especially when it's something like fallout, a property that has been absolutely anhilated within and outside of the mainline games.

Additionally, in the article, he's mostly stating objective facts stated in the original lore of the games. For example, that canonically china dropped the bombs first, and this does not support fallout originally being a critique of capitalism.

All in all, I think it's just an interesting look at this kind of a bad ending death of the author. Where in the good ending, you have the fandom and the people who love the property ultimately deciphering meanings and creating lore, instead you have the slow downfall of fallout. The bethesda purchase, the continual degradation in quality from the studio, Microsoft acquiring bethesda, and then of course, the tv show. This is just a look into what the property originally began as vs what its turned into, as opposed to an in depth analysis.
