Blender is provided for free due to several key factors. As an open-source software, it benefits from contributions by developers and artists worldwide, which helps it continuously evolve and improve. The Blender Foundation promotes education and accessibility by making Blender freely available, allowing students and young artists to hone their skills with professional 3D tools. By offering Blender for free, users globally can propose new features and improvements, enhancing the software's quality and functionality. Blender's development is funded by companies that profit from its use, such as animation and graphic design firms, ensuring its maintenance and growth. The development process is highly transparent, allowing community members to participate in decision-making, which directly reflects user needs and feedback, further improving the software's quality. These factors collectively ensure that Blender remains a high-quality, free 3D CG software.
