Not saying it isn't for nefarious purposes, but the online activation for DJI drones is for their warranty and insurance (or protection plan really). They know when you launch the drone for the first time and give you X days (I think it's 3 or maybe even 48 hours) to purchase some protection plan through them. This way you can't crash your drone and then claim you want to sign up for the protection plan. (Unless it's within the period, then you could scam them, but this does cut down on a lot of fraud)
