This is true. The cases so far have settled. None have gone thru the appeals process to actually generate binding precedent from a high court -they have all been rulings from a trial court judge.
BUT in each case, the judge has ruled as a matter of law that training is inherently transformative and thus not infringing. This is precedent setting, but not binding. Another judge could decide differently -but in doing so would create a matter for appeal.
Where the other cases have diverged is on the other issues. I bring up the Anthropic case because it specifically addressed the issue of acquisition of the data used in the training sets and the impact of that in a trained AI system, which is relevant to this case. The first Meta case (Kadrey vs Meta) also found that training was fair use, but brushed aside the issue of data acquisition; although it delved deeper into the other fair-use qualifiers (amount used, market impact, etc.) eventually finding in favor of Meta.
It could go either way (betting against someone with unlimited funds is not a good bet), but the precedent is against Meta here.
