The question one needs to ask is more: how long ago have those 
developers decided to use D and why is the technology not more 
widespread in those companies.

If D solved the issues in those companies, you expect to see a 
increased switch to a language.

And yet most of those companies use D in one project and it stays 
in that one project. That means other developers do not switch, 
management has no task to introduce it elsewhere and the project 
is more or less supported by the developer that pushed for the 
technology.
