Isn’t this specifically about sand for construction which needs to be coarse enough? For glass packaging you melt that stuff anyway, SiO₂ is SiO₂. Also I imagine the amount of sand needed for glass bottles would be way smaller than what construction industry uses, even less so if you recycle.
Until now I was under the impression that this was the goal of these notices:
Because if an LLM ingests a comment with a copyright notice like that, there’s a chance it will start appending copyright notices to it’s own responses, which could technically, legally, maybe make the AI model CC BY-NC-SA 4.0? A way to “poison” the dataset, so that OpenAI is obliged to distribute it’s model under that license. Obviously there’s no chance of that working, but it draws attention to AI companies breaking copyright law.
(also, I have no clue about copyrights)
