Bias much? An accurate description would be "gcc is licensed such that plug-ins must be at least as freely licensed as gcc is (GPL3) and LLVM is licensed such that proprietary modules can plug in". If that's a "kludge", then it's a pretty "interesting" use of the word, and one that can be applied to an awful lot of software. Further, it's philosophically motivated, not politically. Whether or not you agree with it is a different, and frankly irrelevant issue.
