What's being said here is that current commercial crops of GMO corn are seeing increased yields, and are not causing health problems. (The headline is, as usual, overstating things.) Separately, while you're right that each individual modification needs to be examined individually, the same is true of non-GMO foods, plastics, products, etc, etc. Singling out GMO is foolish. One might even expect, with time, enough evidence to accumulate to be able to answer the ("blanket") question "all other things being equal, does application of GMO as a modification technique cause problems?" Indications thus far are that the answer is "no".
