I'm not sure that the idea here is that spacetime is made up of particles, but that it consists of nothing more than (mathematical) relationships between fundamental bits of information. In a sense, the only things that actually exist are the physical things that populate spacetime. Spacetime itself is effectively an illusion that can only be properly described as a set of relationships between the actual real stuff.

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.
