Even if I agree entirely with the premise, this is not something Open Source projects can use, just like every other restriction on use.
Open Source is a Schelling point ( https://en.wikipedia.org/wiki/Focal_point_(game_theory) ). It's not perfect, but it has the advantage that people can agree upon what it means and what does and doesn't qualify. Once use restrictions like these start cropping up, any non-trivial project would become a maze of restrictions, all different.
And in losing Open Source, we'd gain absolutely nothing. AI training already ignores all Open Source licenses, and proprietary licenses, and complete lacks of licenses. What makes you think this will be respected where every other Open Source license isn't?
