Single Proposition: Two Plus Two Makes Five

For:

The name is not immediately evocative of 1984, the fact that the work is widely known doesn't mean that the trope name isn't obscure.
The name is not immediately clear that it's about psychological torture.
It has been misused to refer to bad math, or odd mathematical proofs that show how two plus two equal five.

Against:

The rate of misuse is small and not worth renaming the trope over.
It is an established term, used elsewhere.
1984 is widely known, and thus this title isn't an obscure name.
A line saying that the page is not about math was added a few days ago; the bad examples haven't been readded since then, so it's possible the problem has already been fixed.
