In a single word: conscientiousness. Simplicity requires a deliberate planning consideration plus additional effort to maintain, often through refactoring once new requirements surface to implementation. For some people these additional steps are essential to main clear output and a single deliberate path forward. For other people these additional efforts are an impossible chore best offloaded to some third party. These thoughts about simplicity apply not just to code but to every decision in everyday life.
