You're forgetting the period of Ruby's popularity in the devops world, especially Chef and Puppet.
Chef you obviously had to, but my impression is that the DSL is so extensive you might as well be writing something that's not Ruby.
Maybe this says something about the power of Ruby, but I don't feel like these tools contributed to the language's popularity or ecosystem - definitely not the way RoR did.
This is just how Ruby is. It's designed around the idea of building DSLs, so writing in Ruby is almost always an exercise in writing in one DSL or another.
