Im going to argue for a hot minute, even if it is "modern slavery", its not. But for the sake of argument, even if it was, so what ?
Its inefficient and nitwits are using it thinking its either Deus ex Machina or a slave, either way
The only practical consequences are data centers gargling drinking water and chatbots causing AI psychosis via next level sycophantism.
Although facebooks been at the latter for a solid minute so id argue that the former is much more of a pressing issue.
