Google tracks you even if you do not have an acccount. There is not practical way to opt out.
I disagree with the TOS but we use their services at work. What am I supposed to do? Quit my job?
Even with ads blocked and cookies disabled, so much JavaScript is served by them, they can infer my browsing habits anyway, and I can't count the number of times I've had to rip 8.8.8.8 out of DNS settings in the last year.
How exactly does this constitute a choice to share my private information with them, and what thing that I want am I getting in exchange, exactly?
