That's ridiculous. Sure, it may be easiest to order from the guy next door, but if you don't like the pizza next door, you can easily call the guy 3 blocks down the street.
My point is you have options when it comes to pizza. There are many types of businesses that simply do not have any options besides Google. Don't believe me? Ask literally anyone who works in digital advertising. If you were planning any kind of digital ad campaign that relied on search, and you said you weren't going to spend on Google, they'd think you were insane. "Oh yeah, I've decided to put all my search ad spend on Bing." It sounds ridiculously laughable just writing it out.
