This, mind you, is not even counting the fact that most JVM implementations and Node interpreters are also written in C++. Moreover every major C compiler (GCC/Clang/MSVC/etc) is written in C++. So any C projects depending on those compilers is indirectly depending on C++, e.g. Linux. Not to mention the success of LLVM among other languages.
