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.
No you can’t. In the same way you can’t watch a Mickey mouse movie and then draw your own Mickey mouse from what you recall from the movie.
Copying can be done manually by memory, it doesn’t need to be a 1:1 match. Otherwise you could take a GPL licensed file, change the name of 1 variable, and make it proprietary code.
LLMs are just fancy lossy compression algorithms you can interact with. If I save a Netflix series in my hard drive, then re encode it, it is still protected by copyright, even if the bytes don’t match.
