The difference is that it's a judgement call when to include attribution, whom to attribute with how much, and overall whether something is too close to be counted as a copyright or other license violation or not. Intelligent humans sometimes, or even often times, have a hard time doing this judgement call. An artificial intelligence would too, and a somewhat simple ML model (no offense) certainly does. I'm really waiting for this to blow up from the open source license angle. Freely combining code with different license is a hellish undertaking on its own. But already just re-using some, say, GPL code, even staying under the same license, but without proper attribution, is Forbidden with capital F.
