If a film or game is constantly changing, which version is the "official" one? Patched media makes it difficult for historians to preserve the original cultural moment of a work's release.
We saw this prominently when Disney+ edited scenes in The Mandalorian to remove a crew member (the famous "Jeans Guy") who accidentally appeared in a shot. Similarly, Kanye West famously treated his album The Life of Pablo as a "living breathing art gallery," updating tracks on Tidal weeks after the initial release.
