This does seem to be the way that Open Source has gone: The operating system and some other critical components (compilers, runtimes, etc) are open source - but applications, services, desktops, marketplaces, firmware, etc are closed. I'd still call this a huge win for both open source and free software. But obviously its a much bigger win for open source than for free software.
