Because the bureaucrats (mostly suits and legal professionals) being afraid of making compliance mistakes in their projects, they will only hire certified people who went through all the German (mostly) BS university education. So the overall system is optimized for hiring rather subservient people and sorts out potentially talented "troublemakers".
In addition, e.g. CCC is one of those groups with well-educated tech talent but they have kind of a history getting criminalized by the German governments (starting from the 80s). As a result, they (to me) seem to be rather anti-government and focus on very valuable tech workshops and tech education for interested civilians.
