Because any company, hypocrisy be damned, will use every legal lever at their disposal to protect their business model.

Hope we are not normalizing hypocrisy, usually it is very destructive.

They can write whatever they want in their Terms of Service. That's the logic.

That doesn't mean that courts will meaningfully enforce it for them.

I understand that, only pointing out the hypocrisy

Well, mostly because of corporate greed of ownership. But the underlying issue is that Ai training in AI is a recipe for ruining the entire training set. At least in these early stages.

Not just greed, they want to silence copyright holders whose works they freely use and at the same time prevent others from using theirs. It is like having different set of rules for them. I don't believe training itself is ruining anything, it is the proposed model of value capture and marginalizing content creators that poses greater threat.

Yes, you've condensed the problem in display quite well here. It's not even just hypocrisy, but also short sighted behaviour.

Artists will learn to not trust the web, if they haven't already. The greatest time to train a model was yesterday, eventually no novel ideas, expressions, art will prosper on the "open" web. Just a regurgitation of some statistical idea of words, and pixels.
