It's still true, five years later. I have my Ph.D. in a related field of molecular bio, and the consumer oriented genetic screening is nothing but a way to separate people from their hard-earned cash.
First, and most important, the science on anything involving multigene inheritance (which is practically everything, including Type II diabetes, cardiovascular disease, cancer susceptibility, etc., etc., etc.) is far from worked out. You'll get results, but even the scientists don't know what they mean yet.
Second, you need a lot of training to be able to interpret those results even to the extent that's valid under current knowledge. The gene screening outfits are not employing excellent genetic counselors to interpret the results. They have software (perhaps supplemented by drones) who match Dot A with Genetic Disorders Database B.
It's not GIGO, because your genetic input is not the garbage. But what comes out definitely is.
