Would Google really admit there was a bug in their search engine? Paid search results is what makes Google the most money. Admitting they can't deliver bug-free results causes people to lose confidence and decide to advertise elsewhere.

Is that so? How would Google search users even learn that Google search "is buggy"?

And unless search users stop using Google, advertisers have no incentive to stop advertising there.
