> Alignment faking occurs in literature: Consider the character of Iago in Shakespeare’s Othello, who acts as if he’s the eponymous character’s loyal friend while subverting and undermining him.

There's something about this kind of writing that I can't help but find grating.

No, Iago was not "alignment faking", he was deceiving Othello, in pursuit of ulterior motives.

If you want to say that "alignment faking" is analogous just say that.
