everyone is entitled to their opinion. and “gross” is subjective (I find feet “gross”, other people like feet). Personally, I think consenting adults (which these models are) should be able to do whatever the hell they want. Our society has this gross obsession with treating adults like we are children, when we are not (perhaps I’m biased because I’m an autistic adult, and those of us that are autistic are especially treated like children by society–it’s insulting to say the least).

Also, I volunteer for a child protection organization (link), and quite honestly I believe that if someone that is attracted to minors “gets off” to adults that look young (which I think might be what you are implying), that’s actually a good thing, because adults can actually consent, and the adults that are involved in adult content, in particular, consent to the erotic nature of that content. I would much prefer that they look at pics or vids of consenting adults, instead of looking at children.
