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.

See, that's exactly what I meant - you are indulged in the aesthetics. FLOSS is very obviously not a "collaboration model" (as evidenced by the whole variety of diverse collaboration models used by FLOSS projects), it's not about licenses and copyrights either; it's all about power dynamics - more specifically, not letting the software creator/distributor constrain their users in unjust ways. GNU GPL does not even require public distribution, it allows selling the software to limited recipients as long as you don't take these recipient's rights away. It's not about collaboration, it's not about being developed out in the open and it's not about preventing the siloing of knowledge aside of very specific contexts - it can be (and is being) used as a tool for pursuing or bettering each of those matters, but these are not its core concern at all.
