I feel like the title is a bit misleading, unless the person who put all HP books on Kaggle as a (supposedly) CC0-licensed data set did so as a Microsoft employee.
Nevertheless pretty egregious oversight (incompetence?) and something that shouldn't have been published.
To clarify: Microsoft linked to a dataset on Kaggle, which is falsely labeled CC0 (Public Domain). It's the fault of the user who uploaded the dataset and misrepresented the licensing.
The original title was "LangChain Integration for Vector Support for SQL-based AI applications"
What makes this different from linking to a random zip file somewhere?
