There are plenty of companies that are switching to Clojure all the time, and feedback is overwhelmingly positive. Here's a recent example https://blog.takipi.com/clojure-at-scale-why-python-just-was...
Again, my personal experience is that my team grew from 3 to around 20 people now all working exclusively with Clojure, and we've never had any problems onboarding, or being ideologically aligned.
Just because it allegedly didn't work out at Amazon doesn't really translate into sweeping assertions you're making about it.
Apple is hiring Clojure people to work on their ML infrastructure. [3]
What's your definition of an inconsequential project?

But as long as we're using personal anecdotes, I saw several teams using clojure at Amazon when it was more popular. Less than two years later, all of them that I knew of (I was a clojure user too, interested in its use in the company, so I was keeping track) were at some stage of abandonment or rewrite into more boring languages. If you're lucky enough to keep your team small and ideologically aligned, it might work for your team, but I have yet to see large company make a significant bet on it (as in more than a few one-off teams) and come out ahead.
