I recall this question being asked in one of his twitch streams(might have been a skyrim one). It is true that the information, the contradictions, the research, etc is definitely useful, but it still cost money to verify the information. It is still saving money definitely, but not sure if it as much as we think.
I would be happy if he destroyed it right in front of him, but then again nick would probably give it to someone in need or donate it or something, Despite acting like the assholes on his livestreams, he seems like he would do something charitable like that.
