In the original NY Times article there's this line: > “Crawling Reddit, generating value and not returning any of that value to our users is something we have a problem with,” Mr. Huffman said. “It’s a good time for us to tighten things up.” So it is "to users" but more specifically it's to our users. I would agree with Huffman here: crawling the data to build ChatGPT gives the value to ChatGPT users who aren't necessarily Reddit users, and by short-circuiting queries and processes that otherwise may have led to new Reddit users, it's taking value from all Reddit users.
