It's in the Matters Arising section of volume 591. These are short 1-3 page long contributions, shorter than research articles. And being so short, they don't have an abstract. Table of contents: https://www.nature.com/nature/volumes/591/issues/7851 https://www.nature.com/nature/volumes/591/issues/7851 As of writing this comment, these short papers (this, and the counterargument, right after in the table of contents) don't seem to be in sci-hub. Until someone uploads them to sci-hub, they probably aren't available in the free web.
