The problem with squirting the oil into the pan as it heats is that the metal of the pan heats up a lot slower than the oil so you will burn the oil before your pan is up to temp. Also, pre heating pans will not harm them in any way at all. It sounds like you’re applying my comment to Teflon coated pans, which I excluded at the beginning of my comment.
Preheating is not an issue. Leaving it on the stove with nothing to dissipate heat for twenty to thirty minutes (during dinner) is a good way to make a fire hazard and get pans past their rated heat. Which results in potential damage to rivets or even layers in the good stuff.
And if your oil can’t take the heat at which you are cooking, it is just burning and adding nasty flavors.
