Why was this link changed? Most of the time that the moderators switch in a link, they are functionally the same, but this is an interview rather than a direct link to the content of the email that was sent out, hosted on the site discussed in the email. Also, the New York Times is paywalled, which is fine by HN policy, but its one thing when the only source of a particular article is paywalled. Its another thing to change the link to the paywalled version... For reference, this used to point to: https://www.thefarside.com/about/48/a-letter-from-gary-larson https://www.thefarside.com/about/48/a-letter-from-gary-larso... It currently points to: https://www.nytimes.com/2019/12/17/arts/far-side-gary-larson.html https://www.nytimes.com/2019/12/17/arts/far-side-gary-larson... EDIT: Looking through what happened, I think the two were merged together as a dupe, but the interview was chosen over the letter itself.
