From a hacking perspective, DJI previously seemed to be pretty nice with SDKs etc allowing you to get the video feed, send controls to the drone etc. But from what I can see they stopped supporting this for most (commercial) drones from Mavic 3 and onwards... Anybody know otherwise?

What I'd want is to be able to remote control it from any other device, it doesn't really matter if it's an Android/iOS app or running on linux/windows.
