I would hypothesize that younger people are less-inclined to feel guilty about using pirate TV services. I think they're also more invested in the future, and aware of dangerous technology's pre-eminence.
I've tried a few times to understand what you're asking. I think you're asking "is it intellectual property theft to train LLMs on artists' portfolios, without their permission?"
I would answer that this is both unethical AND illegal (i.e copyright violation), but kids whom pirate music regularly would pirate both music and art, without regard.
