i’m not saying I agree or care about any of it. A sane company would never allow the use of source code from a third party without a license.

If repo is forked and the license is deleted the source code would need to be hashed to verify its the exact version of an open source repo. Mainly they don’t want copyleft or “malcious” license infecting their IP

If the hashes don’t match then it’s not technically the same code, so a company can’t safely use it without a license.
