Honestly, I'm surprised it took this long.<p>A lot of ad tech is defeated simply because it is provided by a third party, outside the original request, and executed in the browser. So make it first party, use the main request, and build it on the server. It's not as easy, but Google can do it. Make it fast (requires compute + infra) and charge a premium for the placement - after all, it's going to be more "effective". Again, definitely something Google can do.
