> After our initial 0.9.0 pre-release (July 2026), community feedback raised that Coda contained AGPL-licensed code. This prompted a full audit of our codebase and dependencies, and steps to correct what it found. We now believe Coda complies with all applicable licenses. If you have any concern, please open a GitHub issue with the details and we'll happily investigate.
They can remove all of the literal code matches from the codebase, but if it was written by having an LLM study the original code and then write something similar, it's hard to argue it's not a derivative work.
There is a lot of legal history of doing new designs with influence from reverse engineered sources. The basic rule is that you can't have someone familiar with the original code involved with writing the new code.
LLMs are a new area, but I would expect that feeding the original source into an LLM context and saying "Write this, but different" wouldn't qualify as a clean-room design. There isn't enough general removal from the original subject matter.
The difference is that if humans do it, there's plausible deniability that it is derived.
I mean, even when humans do it, we still do clean room engineering.
It goes further though: LLMs are just a tool, and tools don't get rights, humans do.
Humans having the right to learn from a few dozen books and projects is not the same as a tool that infers output using all copyrighted works know to man.
It's not like ideas are protected by copyright though. Copyright protects the specific expression of the idea, not the idea itself. Anyone can "lift ideas" from anyone else, including proprietary software.
Is it a fact that they did that?
So "lifting ideas from other engines", as you yourself put it, is entirely licit, no matter how you do it. _Should_ you credit others when so doing? I err on the side of yes, on that question. _Must_ you? No, there is no such requirement, this is not academic publishing. Does it constitute violation of license? Absolutely not. Straightforwardly, no. Furthermore, it _should not_, we would not like the result of that.
Think: SCO suing Linus Torvalds over his use of a.out: and winning. It would be bad. Even though I understand the reasons for it, it's still eerie to me to see hackers coming down hard on a side of an issue we spend decades passionately defending the other side of.
As I lead this post with: maybe there's something in the repo which is infringing, it's quite possible that commit doesn't tell the whole story. If so, keep in mind that I don't know that, and am able to change my opinion in the face of new evidence.
Based on what I _have_ seen, no: you do not get to lock down a bit-packing pattern just because you're the first to come up with it. Nor should you have that right.

But copyright and plagiarism are orthogonal, and questions of morality are much more tied to the latter. It would be illegal (in the United States) for me to publish a copy of Nineteen Eighty-Four, but not immoral. It was not immoral, in my view, for Aaron Swartz to try to liberate JSTor articles.
That doesn't make plagiarism acceptable, either. And therefore, I'm willing to call it out when I see it.
Now you're demoralized because of... artificial intelligence?
Edit: I'll leave the original bon mot in place. Among other things, I'm curious about your answer to the question. But you deserve a more topical reply as well.
My response in this thread was prompted by @Sp00ph's post[0], which is straightforwardly an accusation of infringement.
You seem more interested in credit, which is a third thing aside from infringement or plagiarism. I would not say that infringement and plagiarism are actually 'orthogonal', perfect plagiarism is, after all, infringement.
Credit is the odd one out of the three. I think it's entirely reasonable to want it, and even to open an issue demanding it (kind of).
But what I want to note about your post: it's hostile. It's aggressive. It's mean. It offers the person you're replying to no avenue to remedy your anger.
I think that's shitty behavior and you shouldn't do that.

Anyway, I don't see how this relates to the original discussion. Nor do I think the irony is particularly deep: As far as I'm aware, Deep Blue didn't plagiarize Kasparov, and indeed alpha-beta search is quite different than how humans calculate. But yes, I'd have been very demoralized if I were Kasparov, although he seems to be doing well now.
Edit: Regarding being mean-spirited, sorry to say, but I don't particularly care for the feelings of someone who has been repeatedly dishonest and used LLMs to respond to people engaging in good faith. That latter path has been exhausted now.
To co-opt your conflation of legality and morality: free speech, mf!

Yeah, it's surreal. It's not just intellectual property either, Hackers have already started complaining about automation now too.
Computers must have replaced tens of millions of jobs. It's the ultimate job destroyer, since it allows capital to do more with less. Automating me, a doctor, out of his job is essentially the holy grail of Hacker News.
But when hackers are automated away, then suddenly it's a crime against humanity.
