How did the editors miss that?

I am sure your entire post is just a 'clever joke' to lure in people's reactions - akin to 'trolling of fish', but instead of fish, you want comments, reactions, provoked responses and so on.

I think the name is wrong for different reasons - 'Deus Ex Machina' is a VERY well-established name trope, which probably comes from some Greek stage plays, where ACTUAL 'machinery' was lowered to save the hero suddenly.

I think it's latin, meaning 'God from Machine' or something like that ('A God from a machine', 'God from the Machine', whatever).

In modern times, it usually refers to something implausible resolving a corner the author of the story wrote themselves in, and couldn't think of an organic way to get themselves (or the hero) out of.

However, removing the 'Deus' (God) from the name, now it just means 'From Machine'. What the heck is that supposed to mean? I don't know, but THAT would've been a valid criticisms, not pretending to mistake latin for english and then pointing out the erroneous spelling.

Of course an english name like 'Ex-Machine' wouldn't really make much sense, either, as nothing 'evolved beyond a machine' in this story. Not that it's possible for a machine to 'evolve' into 'human', for example, but that's something this planet's pityfully simple-minded moronic half-animals don't seem to be ready to understand quite yet.
