I can’t speak for Siva’s and/or Google, but two obvious differences that
come to mind for me personally are:

1) the license

2) there is currently no existing open source implementation of libc for
Windows that works with native Windows / MSABI toolchains.  clang on
Windows, for example, has a hard dependency on a full visual studio
installation for exactly this reason.
