The President hired a person he has worked with before to fill an important job in the Federal bureaucracy. Just like every President before him. You’d rather he picked someone randomly?
You say he should have picked someone who knows everything about aviation (e.g. someone who has spent his life learning to fly, acquiring ratings, working up the food chain to the airlines, and not spent one minute in a management position) for one of the more challenging management jobs in the country? If you want to object to his background, you should be concerned that his experience running one of the busiest airports in the world makes him less GA-aware than we might want.
And for the trolls with spittle-sticky keyboards, what would your response have been if there had been no picture at the top of the article?
