well in the video she was flying the drone in fpv on a fpv drone course and hit one of the obstacles, so i'm guessing she gets to keep it, or maybe she paid for it at a discounted price. she pretty much always gets the latest drone the dji puts out.
DJI stuff is usually to keep, for the reviewers big enough to get them. Others will go buy for a 'unbiased' review, but they would always disclaim that (if they bought themselves)
