Why is D unpopular?

[Dr Machine Code]

It got [asked on 
reddit](https://www.reddit.com/r/d_language/comments/q74bzr/why_is_d_unpopular/) 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
