My rather unpopular view is that if its available for humans to read on the internet, there is nothing different than a machine reading it, other than scale. There is nothing stopping a human from reading your code and using it themselves, or at the very least adapting it for themselves. Unless its a copy or contains actual code you have written then Im not sure you can actually defend it....other than having it locked down on the internet. Of course none of this is tested in court, and my feeling is that once it is, we will end up with a system similar to the robots.txt or maybe even the ML companies forced to attribute work, which would be a major pain for them. Personally Im not sure where I stand with what is right or wrong as I can see both arguments...for example Artists regularly take inspiration from closely studying other artists, producing works from them which is often similar or the same style. Yet this is seen as perfectly ok in the Art world, as long as its not a copy, much of the time they dont even need to say who inspired them. How is this different from AI doing the same thing other than it not being human ? On the other hand someone sees a company making money from something that looks inspired from their art, with no credit, I can also understand how they might feel...its going to be very interesting how this plays out, and at this point either side could win
