Turbo CSS is the web design language of Boomla, the website builder and web application platform. We invests heavily in research and development to make the best product without compromises. To make this sustainable and not kill our core business, we don't want to arm our direct competitors with the tools resulting from our research efforts. So the idea behind the license is to allow using Turbo CSS for all use cases that are not directly competing with our core business. This covers just about all websites out there.
