The dynamics in play is highly questionable. Countless artists and photographers put effort into creating their works. They put they work online to get some attention and recognition. A company comes along, scrapes all of it and starts selling access to the model to generate something that looks highly derivative. The original cohort of artists and photographers not only get zero money or attention from this new endeavor, they are now in competition with the resulting model.
In short, someone whose work was essential to building a thing gets no benefits and possibly even gets (financially) harmed by that thing. Just because this gets verbally labeled "fair use" doesn't make it fair.
Additional point:
Just a few years ago a bunch of tech companies were talking about "data dignity". Somehow, magically, this (marketing) term is no longer used anywhere.
