It hasn't applied to regular people who put on a mask and costume.
It would create confusion to see a normal person put on a mask which is fully emotive and expressive and then have them remove that mask and it becomes a regular mask just lying around and so on. That would raise way too many questions. People would wonder if the Green Goblin outfit works like The Mask i.e. the Jim Carrey movie (or the Dark Horse Comics)? And if that's the case why not ask why don't they animate Spider-Man's face mask to make it as expressive as it is in the comics or for that matter why isn't Batman's face-mask in movies as expressive as it is in the comics or animated series. The point is that these masks originated in a 2-dimensional world.
The Goblin Mask of the Spider-Man films is a distinct looking headpiece, it has a HR Giger Alien looping head curve, and has a demonic frozen expression with teeth, and two golden lenses. It's a scary looking mask that somehow fits with the displays on Norman's rich storeroom, and it also works for the horror vibe as when Norman attacks Aunt May and descends from the night sky like some scary demon (for all the jokes about the mask and so on, nobody has ever offered an explanation for why the costume that's supposedly so bad still works as intended in this scene).
** Not including Ultimate Green Goblin but let's not bring him up, lol.
