cause this is an inspiring act of sabotage
This hurts their colleagues, the many great people who worked their fucking ass off to make this game. The people who crunched for years to get this thing out the door. Imagine working all those days and nights, putting all you have into making this the best creative work you can... and then someone leaks it.
If you think this hurts Naughty Dog as a company much you're living in the land of the fairies. This hurts every artist, animator, writer, musician, engineer etc. far, far more than it hurts Naughty Dog or Sony. This isn't going to stop crunch or injustices in game dev, it just makes everyone's crunch feel like it wasn't worth it.
I've seen first hand how devastating leaks are to colleagues, even accidental ones. For it to be this malicious and this big, it's going to hurt them immeasurably.
You should try living in the real world.
