"Partly blocks" counts every robots.txt whose rules for Diffbot disallow some paths, including generic rules for all crawlers (for example /search); it is not a measure of targeted AI policy. Shares are of the readable websites (W − U: 8,220 websites, 1,659 unreadable); the bounds assume none / all of the unreadable sites block. Solid: daily first-party observations (top 10k of the Tranco list W3ZV9, one fixed cohort). Dashed: reconstructed from Common Crawl (top 10k, sites readable in every crawl), a separate series.
