At times like these, it has become a necessary evil
Calling this a “necessary evil” implies it will make a difference. The people that train AI ethically would ask even without the watermark. The people that don’t will just ignore it.
Note, if you see the light from this close by, it is already too late. And from that proximity. You're already dead, you have maybe a few days to two weeks at best, and most of that time will be spent at the hospital experiencing the worst pain humanly imaginable.
I personally feel greater affinity for Holdfast than CoD, keeping the line with a bunch of other fellows that can get one shotted by a stray musket ball like you hits different. Literally.
