Based on the discussion with our community, we added a clause in our CLA - https://cla-assistant.io/slint-ui/slint - to ensure that Slint will always be made available under an open source license as well as a royalty-free license.
"We believe that open-source software development and communities are the foundation for a healthy ecosystem of high-quality software, where everyone can learn, improve and give back. We commit to upholding this foundation and pledge by promising to continue to develop Slint in the open under an open-source license compliant with the Open Source Definition.
Further, we commit to provide a royalty-free license for those who develop desktop or web applications and do not want to use open-source components under copyleft licenses."
