I have a solution for you.
Step 1- pick a spot on a hard surface
Step 2- apply forehead vigorously
Step 3- repeat steps 1 & 2
Seriously, as long as there is more than one type equipment there will be the types of discussions that you bemoan.
It is what it is.
As to
why these discussions take place I'll offer this- since I am not a machine rest or a very sturdy tripod I need all the help I can get when hand holding the camera to take pics. Higher ISO/faster shutter speed, shake reduction, faster/sharper glass… whatever is available at hand I'll gladly use.
Others may have differing reasons, but that's mine.
