TL;DR: The big tech AI company LLMs have gobbled up all of our data, but the damage they have done to open source and free culture communities are particularly insidious. By taking advantage of those who share freely, they destroy the bargain that made free software spread like wildfire.
If the code used to train LLM was released with copyleft license then there’s only way to interpret how the output should be licensed. There’s nothing absolutist about it, just how GPL and such were intended to work. If you don’t like it, don’t use it to train models.
I think you misinterpreted my comment? I mean the Free Software Foundation is copyleft absolutist, as in, they will defend that model of licensing no matter what. I agree, of course, an LLM can be trained legally with GPL code, as you say that’s how it is.
