Well consider me surprised. I didn&#x27;t see that coming.<p>At first though, when I read through I considered &quot;this is exactly what Stallman didn&#x27;t want to happen with GCC! Companies using the open-source parts to power their own proprietary tools&quot;.<p>And then I read at the end that they intend to submit most of the things they&#x27;ve done back to LLVM&#x2F;Clang.<p>Microsoft is actually starting to act like one of the good guys.
