Spoken like a true LLM!

What you think is obvious is not obvious. Please make your argument instead of insulting people.

I could guess at arguments but the ones that come to mind are pretty weak. For copyrightability, if half the lines in a FLOSS project are public domain, the license will still be effective. For infringement when training, that's not really the user's problem. For LLMs being proprietary, that doesn't infect the output, also many LLMs are not proprietary. For danger, there's not a lot of that specifically in the code-making context, and I don't see how danger makes something anti-FLOSS either.
