That's quite true. Entanglement causes information about the spin of one photon to propagate to another photon faster than the speed of light. That has been verified because the EPR experiment has actually been performed; the distribution of spins of the far photon correlates with the measured spin of the near photon as its spin is measured with different polarizations in ways that would be impossible otherwise.

Except entanglement has nothing whatsoever to do with photon propagation.

As far as anyone knows, the speed of photon propagation also has nothing whatsoever to do with the individual photon going anywhere.
