Those are examples of non-commercial licenses, licenses that grant rights, free of charge, but restrict commercial use of software. When I say dual licensing, I am referring to the business model of offering software for free under a non-commercial license, and charging for commercial usage rights. Kyle E. Mitchell calls this Free-and-Paid Dual Licensing. https://writing.kemitchell.com/2023/09/10/Two-Kinds-Dual-Licensing https://writing.kemitchell.com/2023/09/10/Two-Kinds-Dual-Lic... To use such a business model you also need a commercial license. There's no one-size-fits-all solution, and it's normally something that requires input from a legal professional. Kyle has made a couple of recent efforts to improve things. https://fastpathlicense.com/ https://fastpathlicense.com/ https://commercial.polyformproject.org/ https://commercial.polyformproject.org/
