Microsoft guide to pirating Harry Potter for LLM training (2024) [removed]

Context and Initial Reaction

  • Blog post from Microsoft’s Azure dev site used full Harry Potter novels (via a Kaggle dataset) in a LangChain/SQL vector search tutorial and explicitly described them as a “globally beloved collection of seven books.”
  • Kaggle dataset is labeled CC0/Public Domain, with provenance text essentially saying “downloaded the ebooks and converted to .txt.”
  • Many commenters describe the situation as blatantly inappropriate, “shameless,” and astonishing for a major company.

Responsibility: Microsoft, Kaggle, Uploader

  • Some argue primary blame lies with the Kaggle uploader who falsely applied CC0.
  • Others counter that this doesn’t absolve Microsoft: a “reasonable person” should know Harry Potter is not public domain, so relying on that license is not credible.
  • Debate over whether merely linking to such a dataset is significantly different from hosting it, with several saying Microsoft is still “endorsing” its use.

Copyright Enforcement and Double Standards

  • Strong sentiment that big corporations and billionaires are effectively allowed to infringe while individuals risk ruin from aggressive civil enforcement.
  • Others push back: actual prosecutions of individuals are rare; a few high‑profile cases are deterrent but not evidence that “everyone” is harshly prosecuted.
  • Some think Rowling’s team simply hasn’t noticed yet; others argue massive franchises can’t police every small infringement.

LLMs Memorizing and Reproducing Text

  • A cited study shows an LLM reproducing ~96% of Harry Potter book 1 verbatim when systematically probed, viewed by some as proof models “retain” copyrighted works.
  • Counterargument: what matters is how the system is used (like search indexes or human memory), not mere internal representation.
  • Disagreement over whether this implies the need for stronger “protections for the creative industry.”

Microsoft Process, Quality, and Culture

  • Multiple commenters see this as evidence of process breakdown at Microsoft: devblogs and sample repos appear to get minimal legal/ethical review.
  • Concern that if this slips through in public comms, internal AI training practices may be even more cavalier with copyright.
  • Others note Microsoft historically allowed relatively free, unreviewed blogging to keep posts authentic; they see a single bad judgment call rather than systemic failure.

Takedown and Forensics

  • After HN attention, the blog page was removed (though still visible via caching and web archives).
  • Related sample code and notebooks in a public GitHub repo were rewritten and force-pushed; earlier commits and forks still show the original content, including use of Harry Potter and Asimov’s Foundation.
  • Commenters note GitHub’s signed merge commits make the prior state cryptographically undeniable.

Fair Use, Education, and Legality

  • Some argue using the books here is effectively “educational” fair use, especially for learning how to build RAG systems; economic harm is seen as negligible.
  • Others respond that:
    • This is a commercial corporate tutorial, not a nonprofit classroom,
    • Copyright infringement in many jurisdictions is strict liability (good-faith mistake doesn’t excuse it),
    • Ignorance or mislabeled licenses don’t grant rights.
  • One commenter suggests IP law itself is eroding if such uses become normalized by large firms.

Broader AI and IP Concerns

  • Thread connects this incident to a perceived industry-wide attitude that “copyright is dead” for training data, but still fiercely defended for corporate IP like Windows source.
  • Some see this as part of a broader pattern: “innovation” via breaking or outpacing regulation (Uber, Airbnb, crypto, AI).
  • A few express indifference because they dislike Rowling; others insist personal views of the author are irrelevant to the legal/ethical issues.
