Why is it valid? We have never done so in the 10+ years of working on GCC or LLVM. It's no more valid than me saying "Linus doesn't want to use GPLv3 because he wants to release consumer devices with the kernel and proprietary modules on it". IE it's complete unfounded bullshit with not a shred of intent or data to back it up, and goes completely contrary to the history of his work on the project. In any case, we have no plans to release proprietary modules for clang/llvm.
