It's not that these people would be "totally unaware" if suddenly their searches defaulted to Bing. I imagine it would be disconcerting in the same sort of way that having rusty water shoot out of your shower for a second or two every morning would be. It's not the end of the world, you don't know how to fix it, but after a couple seconds it's not like it really matters.
