News and estimations about Moodle HQ employees vary, but the number is often capped at 50, and only a fraction of them are software engineers. Moodle is not a large company, and a part of its development depends on volunteer contributions. This is often the case for open source technologies, especially when the development is not critical or broadly requested. All things equal, Moodle HQ is better off working on security and performance rather than “cool things.”
