Apple tried "we own the software on your device" argument and lost in Court
Correct.
However where they are on solid legal ground is in their rights regarding any new software they offer as updates for download.
Apple device owners have absolutely no right to that software, and are bound, legally, by the T&C Apple requires in order to download and install it.
The situation here is no different. Why so many of you seem to think you have some claim, and some rights regard new software that DJI provides free of charge is where all the issues are in this particular side-argument.
You bought a product from DJI. That was it. You gave over you money, you got a drone. End of transaction. It is not guaranteed to be without defects, and DJI only provides a limited warranty for a limited time to address any defects, so there's no promise they'll fix anything anyway.
This is no different than every other product you buy, from simple silverware to complex devices like automobiles.
So, this idea that one has a RIGHT to a firmware update, and some vague set of rights as to what can, and can not be included in updates is just ridiculous. It's childish.
DJI provides updates that contain what DJI wants to put in them. There may be bug fixes and features you want, there may be features you don't want. Nothing is being forced on anyone. You download it an install is completely of your own volition.
