It seems to me that the point of the article is that "all the demand" is not just for C++, C, Java, Typescript, Python, etc. There is increasing demand from larger companies for Rust.
No one is forcing you to learn Rust. You don't have to bring yourself spend time learning it. You can keep writing those other languages.
Those languages have been around for a while and they'll continue to be around for a while more. Rust is just getting some time on that stage as well now.
That's the most constructive takeaway you have when looking at all their work? That's an unnecessarily limited view and doesn't add to the conversation.
From my vantage point their work fits the definition nicely.
"A collective body" [1]
...
"Collectivized or characterized by collectivism" [1]
...
"A political or economic theory advocating collective control especially over production and distribution" [2]
