Is this guy actually complaining that Google is taking measures to increase user privacy? Or am I being too cynical/not cynical enough? 'Cause my knee-jerk response is "Dear Marketers, This is why people hate you."
I'm not a marketer but this is a matter of knowing what people want so that they, marketers or their businesses, know what to work on making and selling. It isn't really a privacy issue since Google does track you and know who you are even if you are not signed in.
The marketers are the ones savvy enough to understand that Google has deliberately continued to leave a gaping hole in that privacy protection for its paid advertisers.
Buy ads; you get the data. So it's increased privacy until it hits Google's bottom line. Then, it's not.
