The criticism is exasperation at those who feel entitled to make money off other's copyrighted materials, regardless of what title they might hold. Chat-GPT, Co-Pilot, and Stable Diffusion are algorithms; they are not entitled to learn from any material they want just because people anthropomorphize them and make baseless claims like "they learn just like people do!"
Opt-in would hugely limit the amount of material - possibly to the point where AI research becomes unviable for many applications.
This would impact pure research and other use cases which are likely to be of benefit to society as a whole.
Copyright was created with clear legal limitations (albeit that those limitations are often being eroded by corporate interests).
The "natural" state of man is without copyright and it's imposition isn't a moral right - it's a legal trade-off that should carefully weigh up cost vs benefit.

Not necessarily a bad thing. If your tools require widespread breaking of existing laws, your tools are broken.

Cost: Loss of millions of jobs which are suddenly invalidated by the loss of copyright. Less content overall being created.
Benefit: AI can freely consume what content is left.
I think the cost is far too high.
EDIT: I'd also point out that the "natural" state of man is no laws at all - ownership of goods is enforced with only your strength of arms. I really don't want to live in that kind of world.
Copyright (see the copious evidence that training is not respecting copyrights or licenses across the latest commercial machine learning algorithms).
The same law you brought up? Laws which are written into national treaties?
Regardless of your beliefs about copyright and how it should be changed (or abolished), it is not just the law of the land, it is the law of the world.

That's slightly different. Just because an AI model is capable of plagarism, that's a factor that emerges from usage. The act of training a model hasn't currently been judged to be illegal and neither as far as I know (at least in most jurisdictions) has the initial data gathering.
Creating output that infringes on someone elses copyright is obviously problemmatic and few would argue otherwise. But that isn't a problem specific to AI.
The important part is the opt-in mechanism.
