Why it matters
The two figures address separate defenses. A 20% display rate for grounding content undercuts Microsoft's argument that retrieved web content stays hidden from Copilot users, which bears on how plaintiffs frame copying and fair use. A 99.81% notice-absence rate in the instances examined gives the Ziff Davis copyright-management-information claim a measurable base. If the court lets Goldstein and Delorey testify, plaintiffs can present quantified accounts of display and notice absence as the case proceeds.
