Will it actually? There have certainly been incidents of that sort of thing, but from what i understand people have not been able to reliably make that happen for specific posts .
And yes. I've gotten many free LLM tools and demos to fully recreate stack overflow posts or blog articles. They seem to have a habit of copying comments verbatim which is usually good token to search for to find the original "inspiration."
It pretty reliably does this. The simpler the program you ask for the more likely it is to just copy one. Which we can argue that the simpler the program the fewer the plausible implementations but when it copies the comments so exactly and positions them identically then there aren't any other conclusions to reach.
The current set of "AI" companies are just in the business of whitewashing copyright violations.
Sure, but copying 1 or 2 sentences verbatim into a long program probably isn't enough to win a copyright suit (de minimis). Or at least it would be pretty grey. Similarly, the simpler the program, the less likely the creative intent shines through.
(Mostly im just trying to say these things depend on the details, and the anti-AI crowd tend to handwave the details away. They might still be right, but its far from an obvious slam dunk)
