I think the article is suggesting the opposite to what you are saying.

"quantum entanglement of whatever the underlying ‘atoms’ of spacetime are"

You are arguing Einstein's version of the universe. The disproval of his EPR paper [1] led to the discovery of entanglement.

I don't think I am. Entanglement and nonlocality are the best illustrations of the concept. Rather than spacetime being like a fabric, or an actual thing, it is defined only by relationships. This allows particles to be entangled without being right next to each other. In some sense, that entanglement makes those particles right next to each other.
