I'm sure if that was the management attitude that would have welcomed them, it is a win-win situation.
Not prattle on endlessly about the latest fad.
Rust has some pluses. Yet the evangelism, with the "it fixes everything" lunacy circulating, taints rust, makes legitimate and sane advocates look like nutjobs.
I don't have the time to sort the wheat from the chaff, so when I see a big deal made about rust on a resume, odds are it's a zealot, and into the bin with 'em.
Having a tool on a resume, or listing experience with tools, should certainly not be interpreted as someone being a rust zealot, evangelist, "pratting on endlessly", and all the rest of the examples you gave. So, maybe you initially wrote something different to what you actually meant.
