The reasons are:
* C++ is the to go to language for systems programming
* Any project will choose C++ over D because
     * C++ proven, less bugs
     * There are plenty of C++ engineers out there
* Many tools, platforms and libraries are done in C/C++ making 
C++ the obvious choice.

D isn't more popular because there haven't been much need for 
switching and that projects mostly bet on safe choices.

For bare metal C++ is still the obvious choice but for 
applications I think C++ cannot compete anymore.
