Earlier quoted context omitted.
The legal cases don't mean anything. The rule of law has all but disappeared from the corporate world. The idea that courts or regulators will be able to control AI is laughable. They are too corrupt, and they are way too slow.
The legal cases don't "mean anything" because AI training is /legal/, not because courts are "corrupt". If anything is transformative, an AI that doesn't memorize its input is.
I suspect the answer to the question "is it, though?" is one for the lawyers and lawmakers rather than for the software developers, and it may well vary wildly by jurisdiction.
