It's clearly an unfortunate clash of both DID and Sybil in two separate nomenclatures. Each of which, in its own domain, has different referents.

However, like many of the peer comments here I feel the overlap of these two domains is vanishingly small. Presumably only yourself and a handful of others would even be aware of the etymology.

As you feel so strongly, perhaps a well-written blog post would rank highly for anyone curious enough to disambiguate.
