There is more 20 years of lessons learned between UNIX and NT though. Yeah Linux is a distinct OS but it was written to be a UNIX-clone whereas NT was designed to be a new OS from the ground up. However if you look at NT's spiritual godfather, VMS, that primarily written in C as well. Plus C++ doesn't magically fix the complaints you're making anyway. It's also worth noting that Linux does have plenty of services that support RPCs too (X11, dbus, etc). I'm not try to argue that Linux and Windows are equivalent though. Just that it's a little silly to argue that Linux can't do APIs.
