You are linking to a parody project 🤦
And you are also misunderstanding my point. Yes the cat is out of the bag and companies will absolutely copyright wash their codebases like that, but they have big legal teams to defend against copyright trolls and generally do not publish most of their code base for anyone to see.
Small hobbyist open-source projects that make up near 100% of the projects hosted on Codeberg on the other hand are easy marks for malicious litigation, just like home users torrenting movies were in the 1990ties and early 2000.
