What Hacker News says

Keeping in mind that I'm going strictly off the commit[0], a bit-packing layout is very much the kind of thing which is not subject to copyright in the first place. Neither are algorithms. Ideas, in general, are not subject to copyright: expression is. 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 c

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.

In Born Against, or why hobby programming communities are against LLM usage
The README (https://github.com/adamtwiss/coda#license) addresses concerns about copyright in good faith and better than most agentic-driven repos: > 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.
