My anecdotal impression (I lived in the UK for 3 years) is that not enough companies that adopted Ruby in it's hayday (i.e. 2006-2012) have survived today. Which means, it never caught on with the "enterprise" in the UK, and most of the companies that have survived are still using .NET/Java/PHP. Generally speaking (again, my anecdotal experience), the UK as a whole are tech laggards compared to the US. They'll wait until it gets developed and fixed here, and then adopt it when it's ready. However, as soon as it is ready, they do tend to adopt very quickly (and become quite good). It's no coincidence that Node.js and the startup scene are now synonymously popular right now in the UK and Ruby isn't.
