I know you're going to rebut with saying that iron pans are too, and I'm sure they are, but most people don't want to put in any level of the effort needed to make iron pans as non-stick as teflon.
A lot of people care only a mild amount about cooking, and don't want to invest the time to know how to properly use a cast iron or a carbon steel (which I have and only seldom use). They'd rather get a non-stick pan which lasts a while anyway, throw whatever on there, and never worry about food sticking or cleaning it after.
