That's certainly a way to look at it. And that repo contains a "third party" directory which itself contains Linux, LLVM, and much of the rest of the open source world. But I would suggest that the largest of those thousands of applications probably has a transitive closure of hundreds of millions of lines of code.

I'm aware. I worked on that specific project (assuming we are talking about the same one) back in the day. :-)

There are certainly very large applications in that repo in the hundreds of millions of lines of code. But comparing the entire repo to single applications is not an apt comparison.
