Number of openings is very much not the same as the number of jobs that exist; the article conflates the two, but it's entirely possible that many devs just don't want to work for crypto companies, so crypto job openings stay unfilled (and therefore visible) for longer than other types of Rust positions.

I think you have a point. But the number of openings is a way easier thing to measure than the number of jobs, because you can just scrape public job boards. I think the goal of the post was to bring at least some data to the many anecdotes about Rust being so permeated by crypto (and personal experience agrees with that).
