Does the community / D Foundation have stats about the following 
things:

1. How many companies (big or small) have stopped using D over 
the years and why?
2. What do Netflix, Mercedes, Audi etc. use D for? In-house / 
niche programs, R&D or big real world applications? E.g. do 
command line tools that copy files count as "XYZ is using D now" 
too?
3. Have they continued to use D or was it just a one-off to see 
if it'd be a good option?

It's easy to drop names of big corporations, but it doesn't tell 
us anything, really.

Also, I suppose a lot of companies / people who just dropped D 
again wouldn't tell you because they a) couldn't be bothered or 
b) out for courtesy.
