Yep I've seen seniors/principals come in and steamroll people trying to do FP by claiming that it was inscrutable and irresponsible. Sometimes even going up the chain to cause shake-up without the team's input. Even though said FP was in production, working with a low bug rate, and the entire team was fine with it. And I've seen this happen at multiple companies.
I've come to think it's the biggest existential risk to doing Haskell in industry - it's red meat to org-chart climbing sharks. And the people who tend to be willing to learn and do FP in prod tend to not be politically-minded (usually due to strong principles and values), making them even weaker to these attacks.
