CLAIM-2026-08-31-04

The complaint alleges Anthropic torrented at least five million books from LibGen in June 2021 and at least two million further pirated books from PiLiMi in July 2022, and separately scraped lyrics from MusixMatch.com and LyricFind.com in violation of those sites' terms.

Why it matters

The gravamen is acquisition, not training - which is what distinguishes this from the fair-use question.
