The most telling line in the article was the one by the instructor for a shop that offers the shallow course. He said that, in fact, he had never certified anyone in the shallow version. EVERY one who signed up for it, after the first classes and pool dive, opted to change to the full OW certification. In other words, it sounds like the shallow course is a good way to get folks in the door. I don't have a problem with that, but I do have a problem with limiting the training that OW provides.
I don't have too much problem with resort courses (that's how I got introduced to this sport, after all, and I haven't looked back). The plus for those introductory dives is that they are guided, many times one-on-one (mine was) by a DM or AI. This shallow course turns folks loose to self-regulate with what I consider to be marginal training. I think all the agencies have cut their OW programs just about to the bones concerning content mastery. I am nervous about trimming back any further.
