Microsoft deletes blog telling users to train AI on pirated Harry Potter books

So, here’s a wild one — Microsoft recently pulled a blog post after it sparked a ton of backlash. The post, written by senior product manager Pooja Kamath and shared on her LinkedIn, suggested that developers could train AI models using pirated Harry Potter books. Yeah, you heard that right. The idea was to show how easy it is to add generative AI features using Microsoft tools like Azure SQL DB and LangChain. But here’s where it gets messy — critics called out that promoting piracy isn’t just unethical, it’s a legal minefield. According to Ashley Belanger from Ars Technica, the company quickly deleted the post after the controversy blew up on Hacker News. Now, Microsoft’s trying to clean up the mess, but it’s a reminder that even well-meaning attempts to showcase tech can backfire if they cross the line. And honestly, this raises questions about how big companies handle sensitive topics in their AI development.

Following backlash in a Hacker News thread, Microsoft deleted a blog post that critics said encouraged developers to pirate Harry Potter books to train AI models that could then be used to create AI slop.

The blog, which is archived here, was written in November 2024 by a senior product manager, Pooja Kamath. According to her LinkedIn, Kamath has been at Microsoft for more than a decade and remains with the company. In 2024, Microsoft tapped her to promote a new feature that the blog said made it easier to "add generative AI features to your own applications with just a few lines of code using Azure SQL DB, LangChain, and LLMs."

What better way to show "engaging and relatable examples" of Microsoft's new feature that would "resonate with a wide audience" than to "use a well-known dataset" like Harry Potter books, the blog said.
