I mean... what do you expect from Google, or any internet advertiser for that matter? If 90% of your revenue comes from advertising, getting rid of tracking is like pulling the chair out from under your bum. Having a committee of advertisers sitting on a board governing advertising & tracking in the W3C is going to go about as well as you expect. Conflict of interest: massive.
Their only concern is maximizing their revenue in any way possible, because otherwise they will cease being competitive and go out of business. Ergo this lovely new "Privacy Sandbox" that provides advertisers with a standardized, direct way to get to you. As long as Google or any other advertiser has sway over Internet standards, there will be a fox guarding the henhouse type situation. Moral of the story: don't use Chrome.
