Right now the whole model of generative AI and in general LLM is built on the assumption that training a machine learning model is not a problem for licenses, copyright and whatever. Obviously this is bringing to huge legal battles and before their outcome is clear and a new legal pratice or specific regulations are established in EU and USA, there's no point discussing licenses.
Also licenses don't prevent anything, they are not magic. If small or big AI companies feel safe in violating these laws or just profit enough to pay fines, they will keep doing it. It's the same with FOSS licenses: most small companies violate licenses and unless you have whistleblowers, you never find out. Even then, the legal path is very long. Only big corporate scared of humongous lawsuits really care about it, but small startups? Small consultancies? They don't care. Licenses are just a sign that says "STOP! Or go on, I'm a license, not a cop"
