Which, to be clear, the claim that a standard component is actually unsafe is absurd. Go look at the road bikes people are out riding on a Saturday morning. At least half of them will be disc brakes with quick release skewers. And these are bikes that people are putting thousands of miles on and ripping down mountain descents. I don't have any information on this bike in particular, but that setup is common and widely used.
