I do not mean this disrespectfully but isn’t that taking the idea of “personal freedom” to absurdity? I believe in personal freedom as well but I don’t think walking off a cliff or maliciously using someone Else’s labor is freedom.
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.
I replied to the substance of your comment already, but I also wanted to say that it's a bit frustrating to me that you are downvoted without other replies.
While "freedom" is a fairly generic term (I can be free to kill you or not free to kill you), circumscribing "personal freedom" is reasonable in such situations. Many libertarians would agree that "personal freedom" is bounded by the "Harm principle" so any supposed right to shoot you without fear of reprisal would not be included in the term "personal freedom." Those same people would probably also argue that self-harm (and behavior that places one at risk of self-harm), are absolutely part of personal freedom.
Anarchists might say that "personal freedom" encompasses the right to harm others, and would argue that the repercussions would be natural; the damage to your reputation from harming others would deny you the assistance of others that could be necessary to succeed (or even survive) in the future, and it could also open you up to reprisal.
Some people argue that "personal freedom" includes all, or nearly all forms of free speech. In the US, it is generally agreed upon that defamation and incitement to riot are exceptions due to the harm principle. Many people take it further and say that allowing e.g. a KKK parade in a town should be excluded because it causes harm to the black community by fostering an environment of fear and mistrust, resulting in mental, emotional and financial harm.
I take no disrespect, and agree that a reasonable person could exclude harm to others as part of "personal freedom" I'm less convinced that harm to self isn't "personal freedom" as I think even most of those who support e.g. seatbelt laws would agree that they are a very small infringement on personal freedom in exchange for a very large public-health benefit and are knowingly making that tradeoff.
