I learned how to write code from books I purchased with cold hard currency. In the before times when dialup modems were the norm resources were scarce, and things like Github Copilot were just a pipe dream.
I have also taught classes and provided mentoring and support to new people up and coming in both programming and infosec. I would argue that as an open source maintainer I am actively contributing back and compensating those other developers. Unlike Github Copilot I am not selling the things I was taught, I am freely making it available to others.
It feels very icky that Github now gets to sell what it learned from my code base, when it has already been shown to replicate code with a 100% match, versus learning how to build on top of ideas or finding novel solutions to problems.
