Dozens of people around the world contributed to the early development of powered flight, and even though the Wright Brothers were (probably) first, their excessive and draconian use of patents ensured their work was largely irrelevant to the development of the aeroplane. A lot of other people shared what they learned, which is why many of their machines quickly started to look like our modern idea of an aeroplane rather than the tail-first pusher-prop wing-warping monstrosity that was the Flyer.
I have no problem with giving the Wright Brothers credit for the first sustained heavier-than-air powered flight over level ground, but their subsequent actions had the effect of holding back rather than advancing the field of aeronautics, which is kind of the point TFA is making about Bunsen and patents. The only worse example that comes to mind is Matthew Bolton, who through his sharp business practices and political chicanery only narrowly avoided bringing the entire Industrial Revolution to a grinding halt.
