No healthy minded human being would ever suggest NOT to sue a manufacture for damages caused by their engineering team due to poor programing in the firmware, software or actual product., especially something worth the price range between 1k-4k.
And since when did filing a class action suite cost anyone to get enough signatures?
I am sure you agreed when GoPRo had to recall Karma, maybe DJI does not but have to do recalls and can isolate the issue with their remotes, either way they are responsible for the damages!
