It's a hell no from the Australian judge...
So basically this 'privacy sandbox' will just create a local Google ad agency on my device - not only mining my data to determine my interests and broadcasting interests to advertisers, but also conducting the ad auctions on my own freaking device.
Not content with chewing up bandwidth for all these years, now Google want to chew up gobs of my CPU and power to essentially run their ad business on my device?
P*** off.
