In order for AI to work, it needs a lot of training data. I personally have nothing against AI, just against the commercial variants whose models that aren’t made available to the public.

Of course just putting a license in text doesn’t provide automatic protection. It still needs detection of infringement and enforcement of the license. There’s an ongoing case against at least one commercial AI called Github CoPilot which could set a precedent for ignoring licenses.
