> I hope everyone understand that if you take two entangled photons A and B and detect A before B, then the outcome of the measurement of B must depend on the outcome of the earlier measurement of A, because measuring A causes the collapse of the joint state and determines the wavefunction of B undergoing the later measurement.

This bakes in an assumption that collapse happens, which I don't believe everyone agrees with...

Sure sure, you can ignore that wording. The point is that the first measurement determines the state of the particle undergoing the second measurement.
