Linus is clear in his communication: the license, community, corporations, AI and even Linus himself are there to make Linux better for its users, not the other way around. And as a BDFL, Linus makes the decisions, don't like it, you are free to go. Until now, it has been a huge success, so I am on his side, because I like Linux very much and Linus takes great care of it.
The thing about copyright is complete bullshit. Let's assume AI work is indeed not copyrightable, ok, neither is public domain. And when Disney made "Snow White", the folk tale that is based on is public domain, so, by that logic, Disney's "Snow White" copyright shouldn't be enforceable. Well, try it and see how Disney's lawyers react.
And then there is the part where he tries to demonstrate that AI self reviews (not vibe coding, not flooding maintainers with useless reports) are useless by giving alternative. Yes, the alternatives are good, but it mean that your shouldn't use AI in addition to all that. Throwing every tool you have at your code base is a good thing, a LLM is one of these tools, and it is an effective one as it can catch issues others don't, and also doesn't catch what other tools catch, that's why it is good to use both.
I personally have found many bugs in my code using a LLM. Absolutely no vibe coding involved, not even a single copy-paste from a chatbot, no AI completion, just oldschool code. I had the static analyzers on it, the sanitizers, and the program was quite robust. And still the LLM found bugs, real bugs, enough of them to make me feel a bit ashamed. False positives too, but I still have a brain, I can manage.
It looks like Linus is having the same experience and recommends it to everyone. I can get behind that. In the end you get better code. Can't afford it and you are not enough of a genus to get it right without it, the Linux user doesn't care, so Linus doesn't care either, your patch will be rejected for not meeting the quality standards, which are higher now that a new tool is available.
