I agree that there should have been a "decline to state" option for some questions. But there's no reason why you have to tell the truth.

As far as the usefulness of that question, if Google finds that their market share is decreasing to their competitors, one would hope that they would be more willing to listen to what the survey takers are saying to improve the program and regain market share.
