Well.. Old discussion but I actually think it's the better way (sorry. MIT, you are more free then anything). Either contribute back or stay away from open source work that others did for you.
Can you even copyright LLM output? Even the readme points out humans didn't make any of the code.
This is not the spirit of open source.
Most software is not GPL. When comparing this to alternatives like EGUI and GPUI for building a new app, this cannot be considered, while the others can.
GPL makes sense for applications like Blender. For a general purpose library, it's a dealbreaker.
