> This isn't implied. A particle pair collapsing from a superposition of to one of its eigenstates upon measurement, is a change in the particle in one location that instantaneously affects the other for all intents and purposes.

If you were to use this explanation to anyone that isn't already deeply familiar with how quantum entanglement works, the "instantaneous" part of it would absolutely imply either FTL communication or at the very least the idea of a hidden variable behind the particles at the point of entanglement. And that's assuming they even understand what an "eigenstate" even is.
