They treat customers as unpaid Beta testers, don't pay for damages caused by their failure and they now have the audacity to want to steal your copyright.
If they wanted my copyright they could always approach me directly and negotiate a reasonable price. No they want to take thousands of video clips from hopefuls submitting their video not knowing that they have just given up their copyright to DJI in return for a chance to win 1st prize. Not at all a bad deal for DJI - copyright for less than 1p for 5 mins of your video they will use in advertising they would have had to pay thousands to professionals to create.
Don't get me wrong most of their stuff is excellent but support is almost nill, customer care is nill, their prices profiteering and all they want is more of your money as fast as they can along with your copyright.... Greed... Greed.... Greed and nothing else in return.
