Yes, I've seen that article and I'm familiar with this industry. Are you suggesting that people aren't buying drones? They are. They're just buying them (mostly) from one company, DJI, that in 2017, had revenue of over 2.8 billion dollars. To suggest that consumer robotics is not a thing because DJI has dominated the market is akin to suggesting that operating systems weren't a thing in the 90s.
