Tools like EULAs end up being fairly coarse in practice.

Presumably the Zig authors prefer a world in which it is possible to maliciously use the tools under MIT, and non-malicous actors could do various things downstream that the GPL would be a barrier to, to the world in which the GPL prevents both of those things.

There is a cost to preventing harms, and people will disagree whether the cost is worth it. There are many evils in this world that I do not push for collective action to eliminate merely because I do not yet see a feasible solution that is worth the cost. That doesn't preclude me from individually speaking against those things, warning people about the pitfalls of them, and shaming those who do them.
