The trouble with Eliezer’s “metaethics” sequence is that it’s written in character (as a human), and something called “metaethics” shouldn’t be.
People always write in character. If you try to use some different definition of “morality” than normal for talking about metaethics, you’ll reach the wrong conclusions because, y’know, you’re quite literally not talking about morality any more.
Language is different from metalanguage, even if both are (in) English.
You shouldn’t be using any definition of “morality” when talking about metaethics, because on that level the definition of “morality” isn’t fixed; that’s what makes it meta.
I can’t make sense of that. Isn’t the whole point of metaethics to create an account of what this morality stuff is (if it’s anything at all) and how the word “morality” manages to refer to it? If metaethics wasn’t about morality it wouldn’t be called metaethics, it would be called, I dunno, “decision theory” or something.
And if it is about morality, it’s unclear how you’re supposed to refer to the subject matter (morality) without saying “morality”. Or the other subject matter (the word “morality”) to which you fail to refer if you start talking about a made-up word that’s also spelled “m o r a l i t y” but isn’t the word people actually use.
My complaint about the sequence is that it should have been about the orthogonality thesis, but instead ended up being about rigid designation.
I remember it as being about both. (exhibit 1, exhibit 2. The latter was written before EY had heard of rigid designators, though. It could probably be improved these days.)

You should use a definition, but one that doesn’t beg the question.
