Well, when St. Linus Torvalds said those words, (1) g++ was not as good as many other C++ compilers, (2) the world was still full of very bad examples of C++: if you were lucky, back in those days you could have found some projects using C++03 but the majority were stuck to C++98 -- or worse -- and, (3) he called out the holy principle that "at my place, I make the rules". I do not think that in 2016 there are good reasons not to use C++ for an operating system. Even without using the STL -- which would require custom allocators at that level -- incapsulation of data inside objects, inheritance, templates and namespaces alone are a reasons good enough for me to prefer C++ over C at any time nowadays. In 2016, that is more a cargo cult not to use C++ for operating systems implementation than anything else.
