They've also been asking for birthdays lately, obstensibly to verify age, but with the small print that it will also be used for ad targeting. But don't worry, they say, you can control how your information is used after you add it. On that page, the only option is whether to show the birthday publicly or not. There is no option to disable use for targeted advertising.

Oh yeah, and Google frames asking for a birthdate as being "in order to comply with the law". They are deliberately ambiguous in order to imply that it is me who could be breaking the law, rather than Google. Also, the law only requires verifying age, and doesn't require storing the birthdate afterwards. That one is entirely on Google.

So overall, my trust in anything that Google claims is rather low.
