>wanting the freedom to copy artists’ works when using it

Learning from copyrighted content is legal - for both humans and AI. If Meta is in hot water for anything, it's piracy and/or storage of copyrighted material.

By ”using it”, I mean using the AI model.

Huh? Then that's even more straightforward, and your comment from late 2022 doesn't hold up at all. So, unless you're specifically going out of your way to break copyright law, inference is totally fine.
