When is D endorsed by Facebook?

[rom via Digitalmars-d]

Hi all.

Sorry if I put the foot into it, but when is Facebook going to 
use more D based programs ? Why don't they do that ? because  std 
functions use the GC ? What happened since the end of 2013 ?

I feel like we miss manpower, renown, credibility... and i think 
it's such a shame, because D is the best language i know of  ...

It's quite known that a language greatly benefits from corporate 
backing, am i wrong?

So what is the rational at Facebook? Are they going to wait D' s 
dead to endorse it?

Thanks for any clue or even better, an answer ?
