Some of it is because many people's only contact with Lisp is via academia, and the academics who teach it actually don't care about developing anything with Lisp. They use it as a vehicle for concepts, and those concepts typically revolve around functional recursion.
The Scheme language and it surrounding culture are also culprits. Though Scheme isn't functional, it emphasizes pure programming more than its Lisp family predecessors. The basic language provides tail recursive constructs instead of iterative ones, and demands implementations to implement optimized tail calls.
