You can replace DJI with any other consumer electronics manufacturer. It's hard to compete with China's vertical integration + cheaper labor. Skydio (Californian startup) used to manufacture consumer drones but recently exited that business to focus on enterprise, probably because of the higher margins.
DJI is particularly hard to compete with, because it is a very reputable and highly sought after company to work for and thus gets the brightest Chinese engineers on top of everything else you mentioned
