It’s interesting as to 3 camps
one is the try and do right or what the current consensus is on what’s right morally and ethical if not legally required
two is not caring ether way
third, people who enjoy twisting the knife, troll if you will.
most fly fishermen I have known are more ethical than most, I am sure the gentleman intent was honest, the fish was post likely a goner before he did the Gil flap hold...that being said mishandling fish is a big no no these days....carp, muskie and even bass holds are even criticized....I even see guys post filleting a muskie just to enrage folks...sadly the fish died, been cooler if he lived and was caught again bigger....Frank comes to mind...
