<span style="background-color: rgb(255, 255, 255); text-transform: none;">That is about training data, which I agree is debatable (TDM, fair use). My concern is RAG. In a production setup, the database stores my text as chunks of the original sentences plus
vectors for retrieval. The chunks are verbatim copies, kept precisely so the model can retrieve and reproduce them. </span></div>

<span style="background-color: rgb(255, 255, 255); text-transform: none;">Under the license definition, that database would likely count as associated data, part of the
<b>Model Materials</b>. So claiming my own work back means claiming that the Model Materials infringe my copyright, and Paragraph 5 ends my license. Note that Paragraph 5 says "<b>any person or entity</b>": any compute provider who deploys the model and stores
user inputs can use the same clause against a user's claim.</span></div>

Let me make it concrete. Very few users can self-host an LLM today; most depend on cloud deployments. Suppose a database cloud service stores your private data to improve the experience of its users. Under this license, that data likely becomes part of the
Model Materials. When you sue for copyright infringement, your license terminates, and your entire business, which runs on that model, goes down with it. Does that still look like an open source license to you?</div>

if I hold a patent that could threaten Mozilla (I have none). What I do have is a lot of copyrighted content, and I think most people do too. I am not saying it fails the OSD. I am just saying that, as an Open model license, 1.1 looks more aggressive than
MIT. As a developer, I would avoid models under it.</span></p>
