"If you copy my work, you should share your work too."
or at minimum (MIT):
"If you copy my work, you should credit me."
I think it is no longer under dispute that the legal contract is satisfied by LLMs. The AI companies won and will continue to win.
But we are talking about a social contract, which is not quite the same thing. The social contract is what leads some devs who previously enjoyed publishing their work openly to no longer feel the same way. What did the authors mean by "copy"? Did they mean literally CTRL+C, CTRL+V or something broader?
This is a matter of opinion which only each individual creator can answer. For me, copying meant something like:
"To reproduce the function of my work, dependent on my having published it, without effort nor understanding of your own"
Ten years ago this basically required doing a CTRL+C, CTRL+V so there was no need to be more specific. Anybody who did enough work to, say, rewrite in another language (with that language's idioms), met the bar of clause 3. Now AI enables a form of "copying" that matches my definition, without the user even being aware of whose works they are copying. It perfectly launders the origins of its output. It can write an FFmpeg clone in Rust for you that would appear to be a novel work.
Of course, I cannot say that my own little bits and pieces of open source code would make a scratch in AI's capability, were it removed.
But I do strongly believe that if all the code that was published by authors with the same mindset was unavailable, Claude would be a far weaker developer.
Attribution is often required even on MIT or BSD licenses where code is being redistributed, either in original or modified versions, but that would relate to this discussion only to the extent that one regards using LLMs whose training data included a certain bit of code as itself constituting redistribution of that specific code -- but that in turn is a very debatable premise which really ought to be argued for, and not merely argued upon as though it is already generally recognized as true.
