The question can be why C++ programmers like RUST but not D.

RUST achievement:

a) browser engine (firefox,  webrender)
b) Virtualization (firecracker, rust-virtual-machine, 
cloud-hypervisor, railcar , vagga  )
c) database, storage engine (tikv , PumpkinDB, sled, indradb, 
noria, ParityDB)
d) Emulators / Games / Graphics / Text editors (a lot projects on 
github with active users)
e) System tools (there is really a lot on github)
f) Web developer, WASM projects
g) betters IDEs support
h) BlockChain (Facebook Libra, and a lot other products worth 
millions or billions)
i) Android and IOS. (D has Android, but not IOS)

D has similar projects for web/wasm/GUI, but with less projects 
activity and users.

I suggest D should add a grave yard page with dead projects on 
this site.
