The top link gives my the same URL, but now I don't need a login. I wonder if NYT checks the referrer, and since mine was Google it let me read the entire article.

Apologies for any inconvenience or confusion. If you click the Google search link above and follow the reference it may well work for you. In future I'll extract the link and open it in a clean browser just to be sure.

Thank you for bringing this to my attention.
