It is a source targeted at the general public, which unfortunately does not know enough to hire a competent columnist. John Cramer has used the wrong equations to arrive at an incorrect description of the Afshar experiment, which he uses to justify his own interpretation of QM, which he wants to be correct. The experiment is not in conflict with the known laws of physics.
In general, I advise you to mistrust reports of recent developments in physics, if you have no physics training. I check a number of popular sources occasionally and about half of the articles are either wrong or misleading. For example, you may have recently heard about Erik Verlinde’s theories about entropic gravity. If gravity were an entropic force, gravitational field would cause extremely rapid decoherence, preventing, for example, the standard double-slit experiment. This is obviously not observed, yet this theory is one of the more well-known ones among physics fans.
