Is there any reason for Tongs

When I feed. I get both my wtf on a platform I have in my tank, then after I dust the crickets I just pinch them and hover them by which ever frog I’m feeding mouth. I do that for a few crickets each then let the rest loose in the tank so they can hunt for them. My frogs are really friendly and they will jump on my hand if I’m doing anything in the tank. But I mentioned my way of feeding to a couple people and they criticised me for not using tongs. I said that although I’m not scared of the crickets I do still wear gloves when feeding them since I always wear gloves holding them, I was still told that I’m feeding them the wrong way. I don’t think they know what there talking about but if there telling the truth could someone explain how it’s bad for the frogs.
