>Now the "official" YOLO will release v6 and then what
I agree that it's disrespectful, although FYI the 'official' YOLO is done - the author, Joseph Redmon, has quit the field[1] because of the military and privacy concerns of CV.
Tip: you don't change the system, the system changes you (or uses you and spits you out) especially when talking about military applications. Refusing to work is the only way to make a difference via your job.
It's a function of how much you tend to perceive yourself as effectual. If you think the world is already a lost cause then you let it rot and try to keep away, if you think you can make a difference then you stay and try.
Good on him! :)
