That’s many new words for me, seems some groups of people also have no usage of words that others use!
I value software freedom; basically being in control of your own computing. I dislike others taking my code and then denying their users the same freedoms they enjoyed. If not for that I could do without most of Copyright as it is today.


People sue companies that take our code and redistribute it while denying their users the freedoms we indended for them (via the software license). We call it GPL enforcement, or copyleft license enforcement. https://sfconservancy.org/news/2015/oct/01/compliance-principles/
