Those who are against superluminal communication often choose to look at a single set of 'entangled' particles as an example of communication between A(lice) and B(ob). For example, Patrick Van Esch: 'EPR, density matrices, and FTL signaling' that sees the two particles as ‘clearly defined subsystems’ - which seems surprising if they shares a common superposition.
Would it not be more appropriate to look at a communicative situation which taking some time and are based on agreements between A and B?
For example:
A and B are measuring corresponding particles from pairs of quantum mechanically entangled photons - so-called Bell-couples.
The distance between the transmitter and the source are suitably much shorter than between the source and the receiver, so with synchronized watches the transmitter will detect its twin particle before the other twin reaches the receiver.
The transmitter can change its measuring setup by inserting a mirror or not – choice situation, T(1) or T(0). It keeps its choice for an agreed period – for instance 1 / 300.000 sec.
The receiver has a fixed preset setup. It should by measuring its part of the pairs with at least 99% probability, guess the Transmitters choice.
As the exchange between the entangled particles takes place instantaneous it will for a growing distance between A and B create superluminal communication.
