RMS has a ideology of what free software is that ignores how much 'free' software actually gets delivered to users. As an example XCode is not free but since Apple can make an ecosystem around LLVM/clang it creates the profits necessary to pay developers to put lots of work into LLVM/clang that people can use under a BSD/MIT license. RMS has a kind of natural law approach to freedom while most 'free' countries have a limited amount of freedom that people give up in order to have an organization that guarantees the remaining freedoms. RMS is much more concerned about maintaing ideological purity than implementing a less ideologically pure system that may or may not benefit users more. Fundamentally once GNU code supports clang, GCC dev stops because it's codebase a horrible mess.
