Not sure what the point is - the headline reads "Confirmed: DNA From Genetically Modified Crops Can Be Transferred Into Humans Who Eat Them" - well....yeah...you eat a plant het DNA goes inside you....and??
the abstract from the linked PLOS article reads:

Our bloodstream is considered to be an environment well separated from the outside world and the digestive tract. According to the standard paradigm large macromolecules consumed with food cannot pass directly to the circulatory system. During digestion proteins and DNA are thought to be degraded into small constituents, amino acids and nucleic acids, respectively, and then absorbed by a complex active process and distributed to various parts of the body through the circulation system. Here, based on the analysis of over 1000 human samples from four independent studies, we report evidence that meal-derived DNA fragments which are large enough to carry complete genes can avoid degradation and through an unknown mechanism enter the human circulation system. In one of the blood samples the relative concentration of plant DNA is higher than the human DNA. The plant DNA concentration shows a surprisingly precise log-normal distribution in the plasma samples while non-plasma (cord blood) control sample was found to be free of plant DNA.
so what they are saying is that bits of DNA can get into eth blood stream that are bigger than was previously thought possible, but they don't know why or how.
Presumably this has actually been happening forever, so as you say, we haven't turned into non GMO plants despite having been eating them for 100,000 years - I cant' see much changing in that respect any time soon - even on a geological scale!!
