This transparency is "hot" because it empowers learning and innovation. A graduate student can modify a 2D plane-stress solver to include plasticity by editing a few lines in the computeStress.m function. A researcher can test a novel element formulation (e.g., a mixed hybrid element) without waiting for a commercial vendor to implement it. The M-file becomes a living laboratory.
