GoPro was very late to the game and isn't really an R&D company, they're a marketing company that gets others to design their cameras IIRC, so they had almost no chance of taking on a company like DJI that had a very strong R&D culture and a big head start.

I really like my DJI drone, it's almost too good to the point it's boring. But it's still easy to be concerned about the political issues with the company, and in some cases the company has overstepped it's boundaries a bit too far in terms of choosing safety. Their setup is basically setup for false positives where a false positive means you can't use the drone at all in a place where it is actually legal to fly if you follow the local laws.
