I think this policy is yet another example of ethical overengineering.

Yes, of course, ChatGPT & Co. are very unlikely to take any real care about what they give their models to learn - especially with regard to copyright.

For a better perspective, I always try to transfer the behavior to the analog world. In this sense, someone who, for example, illegally obtains a book on Linux (let's say via ebook) would not be ethically in the correct position to contribute to Gentoo, because the knowledge on which their contribution is based would be stolen intellectual property.

I can't imagine that there are any people in this world whose knowledge was obtained exclusively through copyright legal means. We are all in a gray area - one possibly more than the other.

In my view, it is typical of engineers to simply transfer philosophically complicated moral issues to technologies. But this method will never come close to solving anything, because the very complicated analog moral world cannot simply be mapped to 0 or 1.
