It's not bad, it's wrong, since they make reference to the "entangled photons in the light coming from the quasars," which is entirely not how the experiment worked. The light from the quasars (which weren't measurably entangled with squat!) were essentially used as random number generators, in order to perform standard Bell test experiment [0] using a standard laboratory entangled-photon source. I recommend reading the paper instead, if you're interested [1].
