There is a significant anti-Ruby sentiment in the tech industry right now, especially in certain fields like InfoSec, that is being pushed by a very vocal subset of the community. Whenever they see Ruby come up, they will try pushing the meme that Ruby is dead/dying/irrelevant and cite TIOBE; despite Ruby developers continuing to release new libraries, frameworks, and tooling. Or they will claim no popular websites use Ruby; apparently GitHub, LinkedIn, and AirBnB are not popular enough? Or claim MetaSploit is the only security tool written in Ruby; off the top of my head I can think of BeFF, CeWL, Evil-WinRM, and Ronin. Or claim no company uses or supports Ruby; GitHub, Shopify, Stripe all use and support Ruby. Or they will derail any positive discussion about Ruby into some intractable debate about Static vs Dynamic Typing, GC, interpretive languages, etc; even though many of the arguments against Ruby can equally be applied to Python, and yet there's no similar criticism of Python. It's really annoying and inconsistent.
