I'm looking to release some code as open source but I want to ensure that my work is not licensed for the usage of immoral and/or illegal purposes. In section 5F of the CPOL, it addresses these concerns of mine. However, I would like to add specific examples of things included in the definition of "immoral", such as pornography, discrimination of race/ethnicity/religion, etc. I would state it something like "Immoral and improper purposes include, but are not limited to, ...".
Am I allowed to make these changes to the CPOL and use it for my projects or do I need to either find a license that states these things or just create my own license?
