I think it is based on DJI experience vs GoPro experience in the drone world. Karma concept is a very good one and something to keep watching. But it has not reached yet the more advanced market as far as the drone part is concerned.
From what I've seen the Karma seem to have a lot of problems, like it won't stay still when hover, but that being said I'haven't had my hand on one, so I could be wrong.
