I’m not saying this is aligned with FLOSS, FLOSS is a collaboration model. I’m saying the outcome of easier access to knowledge should be celebrated by supporters of FLOSS. Licenses and copyright aren’t good for their own sake, they’re tools for increasing people’s freedom to use, study, modify, and build on existing software. LLMs are another tool for increasing people’s freedom to make new software or improve existing software.

You don't seem to understand what FOSS is really about. The GPL has always been about the user. When a company license-washes a existing GPL software project and turns it into a proprietory product, the resulting code is not "free" anymore in the sense that the user has lost control. This is exactly what the author wanted to prevent in the first place by licensing their code under the GPL.
