Don't use google then
If all you google haters are so against Google serving you ads based on your surfing habits, don't use google. Google is free, and it works really well. Don't complain about free things! They make money from advertising to provide you a service. If you don't like how they make their money, don't use their free services.
Read my email? Yes, i'm very sure Google is interested in reading the emails of a few hundred million people.
There's a difference between reading an email and parsing an email. I definitely mind a human reading my email, but if a computer was parsing it looking for keywords to decide what ads would appear on the page, I really, really don't care. How does it affect you? Apart from paranoia.
What's to prevent any internet company from doing the same? They all have access to your email.
Steal my passwords? What, you're all using the same password for all your accounts? tsk tsk.
Bottom line: You google-haters aren't as important as you think. Nobody really cares enough about you to bother to sit down and read your email. You're not that interesting. Really. Paranoia paranoia paranoia.
Did you know that word processors ... read ALL your documents? How else would they know when to put a squiggly red line under mistyped words? Not to mention, online spellchecks on other webmail providers! GASP!! Oh... oh wait... there's a difference between a human reading what you write, and a dumb computer parsing information. Saying "google reads all your emails" is deliberately misleading to instill paranoia in those who like to sensationalize things. Google doesn't "read" your email like a human does. Computers don't "read" things. They recognize things. OCR isn't called Optical Character Reading for a good reason.
Still paranoid? Don't use any google products, and stop trying to "convert" people by sensationalizing things. Don't even use google products through an anonymizer if you're against the way the company makes money to provide you with that free service.
