I don't understand. My vote is meaningless; I've never decided an election. If an election is close enough for one vote to make a difference, you can bet that it will go to the courts. So it sounds like what you're saying is that if I don't like the government, my options are expensive and/or ineffectual, whereas if I don't like Google, I can spend a fraction of a second switching to another search engine.

Of course it's getting harder to avoid Google! But it's still possible, if you feel that it's net beneficial. I think another way to phrase your argument is "By using my personal information to target ads and create more valuable search results, Google can subsidize some amazing products that I love. I would prefer to live in a reality in which such products exist, but can be paid for through some alternative means. Give me that reality, please." Or you mean "It's not worth it for me to use Google products, so I don't."

This isn't like participating in politics; you can actually make a difference. Is Google worth it?
