Actually, I was trying to address "The Copyleft licenses work around that and make cooperation between of adversaries possible" to show that a more "BSD-like" license like LLVM have many "adversaries" collaborating: researchers, enthusiasts, and otherwise competing companies. This is a rebuttal to "It would be another BSD with not many commercial players contributing to. BSD-ish licenses mean free labor for companies, but are problematic for cooperation".
