I suspect this is the end of the Karma,we have to have confidence in our aircraft, and falling out of the sky is one of the worst experiences. I still get nervous when flying(A good thing as complacency is bad), but I have developed a good confidence in my P4.
I think I would be very wary flying a Karma, despite a few early warnings about the Mavic, DJI have won hands down.
As others have noted it is good to have competition,helps innovation and keeps price down, but a bad product will damage the hobby as a whole.
