On the scale of bad ways to do it, this is pretty low. The fish wasn't pulled 20 or more feet up the bank across a series of rocks, lifted for a photo, examined by 5 'experts' to determine if it's a keep-able species and then released after being out of the water for over a minute was it?
Sure better to keep it in but it went back in the water fairly quickly.
I really don't understand this kind of shaming. Perhaps it would be better to have a short chat than record and post?
Having fished local rivers for over 50 years all I can say it was always bad. Snagging was proliferate and many snagged and non-retainable species taken in the 60s and 70s, perhaps more commonly than today.
