Maybe I can shed some light here, but maybe it's also just arguing on the internet... The problem is the following: imagine you're an artist with a physical shop. People go to your shop, they like your art and take pictures of it with their phone. That's the second best thing that can happen to you. (after someone buying your art or hiring you for commissioned work ofc). Bc the artist gets popularity from it. Now imagine somebody sets up a new storefront in front of the artists shop. Shows the artists work, but takes away the name. Says they can commission any piece that's like the artist's work, but for free. The artist makes no revenue anymore. They don't get popularity, bc the new shop shows it's own name and hides the artist. Now the artist goes bankrupt. The fake store front moves over to the next artist's shop and repeats the trick. Until they're all out of work.

Many artists like piracy. Bc it means people talk about your work. It gets shared and makes you popular, which inevitably leads to more buying customers at some point. Ai scrapers though mean you're not gaining in popularity anymore. So you starve, and that's the problem
