The New Yorker is a magazine, and not a news outlet. By definition they are an analysis publication—that means their articles are essentially opinion pieces. They have no journalistic obligation to post sources.
Your positing that its about money might be correct, but for different reasons than you suggest. News and magazine publications often do link to a number of different documents.

The situation isn't so black and white.
