I recommend reading this article by Kit Walsh, a senior staff attorney at the EFF if you haven't already. The EFF is a digital rights group who most recently won a historic case: border guards now need a warrant to search your phone.

AI training isn’t only for mega-corporations. We can already train open source models, and Mozilla and LAION have already commited to training AI anyone can use. We shouldn't put up barriers that only benefit the ultra-wealthy and hand corporations a monopoly of a public technology by making it prohibitively expensive to for regular people to keep up. Mega corporations already own datasets, and have the money to buy more. And that's before they make users sign predatory ToS allowing them exclusive access to user data, effectively selling our own data back to us. Regular people, who could have had access to a competitive, corporate-independent tool for creativity, education, entertainment, and social mobility, would instead be left worse off and with less than where they started.
