Okay, I'm surprised I'm saying this, but this comment is rather... ignorant in nature.
First off, the plates aren't really all that bad. They're no different than refined iron, just needing to be pounded into a plate instead of cooked again into refined iron. Granted, the hammer's durability is laughable at best, however the concept isn't really that bad, and you can make a machine to automate it.
Second off... this is their project. They own it. You can't fire either of them, because a) they are not being paid for anything, b) because they do not have anyone in an authority position to tell them to in general, and c) because you in specific don't have any authority over squat regarding this mod and the devs working on it.
Disagree with the mechanics all you like, I have my own reservations on it. However the comment about 'firing' the guys who are in charge of the mod is just... it is an incorrect term being used. It is like trying to fire an author from writing his book series.
Don't like it? Don't use it. I know I don't. But that comment is just so... ludicrous... that it is only going to invite retaliation. If I had even the slightest suspicion that you were unaware of what you are speaking of, I'd call it deliberately flame-baiting. But since I am firmly of the opinion that it is out of ignorance rather than malignancy, I can only suggest you not use such a phrase again if you ever wish to be taken seriously on any topic ever.
