LINQ is simple, but it represents a way of thinking about computation that is wildly different from what has historically been available on popular programming languages, and interacts poorly with how most people are taught to program. I see the same thing when teaching people to program for Apache Spark (which took inspiration from DryadLINQ). They keep wanting to do things in an imperative way. It typically results in unnecessarily complicated code, and it always interacts terribly with the computational model. But it's also the way they've been conditioned to think over years or decades, and, from what I've seen, is often so deeply baked into their thought process that doing it any other way is, at best, deeply uncomfortable.
