Why is D so unpopular?

[spice agent]

It got asked on reddit sub but for those that aren't active too, 
I'd like you opinions. Please don't get me wrong, I also love D, 
I've used it everywhere I can and I'd say it's my favourite 
language (yes I have one...) but I'm as as the reddit's OP, 
trying to understand why it's unpopular. Rust and Go seeming to 
be getting more and more users. I think it's due to large 
ecosystem and the big corporations with deep pockets that pushes 
them. But I'd like to know you all opinions
