I cannot speak for any company, and IANAL, but the big problem that I see in the current situation is that we can’t freely move code between LLVM and the runtime libraries, and we can’t share code between LLVM and the runtime libraries, because we address the runtime exception by having a different license for the runtimes than what LLVM and Clang are licensed under.

Moving to this modified Apache 2 license for all our projects seems like a clear win to me.
