This ship has sailed for academic publications, and academics define that term very liberally because we want to read everything, fiction included. The shadow libraries started off as a way for scholars in ex-Soviet countries in particular (but also India, SE Asia, etc.) to access literature that simply wasn’t available in their country. But the shadow libraries proved so successful and convenient that academics in all countries are using them now, even if they have access to official subscription services. I use AA several times a day and so do the researchers around me in my office; at conferences, if the presenter mentions an interesting publication, the whole room immediately opens AA on their laptops, etc.
Even if projects like AA didn’t have nation-level support, academics would find a way to keep as much of it as possible going. After all, we’re the ones who compiled the bulk of pre-2020 material, and we’re the ones who do all the hard work of scanning from our institutional libraries stuff that doesn’t exist anywhere in digital form.
