This is just silly. You can't say that you can pull the code from a public repository, and then claim it's private. If it's set up so you can pull the code, and you do so successfully, then it's by definition public. It's totally understandable that you're unfamiliar with how the the projects and dependencies are distributed. The Chromium projects are one of the largest and most complex codebases you're likely to encounter. However, it's all clearly documented and public, with numerous open source contributors. So, it's very disturbing that your first thought is not try and learn why, but rather to insinuate some irrational conspiracy theory.
