Yes, there are differences between those things.

Poaching is cooking in hot liquid, but the liquid is not boiling or even simmering, so it is a lower temp than both.

Saute generally means you’re using a small amount of oil/fat and stirring/tossing the food to spread the oil/fat around on everything while cooking everything. Pan frying generally means you’re cooking a larger piece of something and not tossing it around.

That’s not really relevant to the question being asked and the answer you’re replying to though. OP said straws should just stop existing because it’s only a convenience, and this counterpoint was that there are people who NEED straws, not as convenience but as necessity.
