agree - but that gets to the larger point that mass adoption of anything like has to be fairly frictionless.
We are barely getting a third of people to use adblockers - you'd have to squeeze the ad server industry a lot more to make them change.
How to squeeze them? Get more people to use an adblocker that enforces serving from the same domain. How to get more people to use an adblocker? Make it frictionless, like enabled by default on browsers.
Then by squeezing them, they would be forced to respond by building tooling making it more frictionless to serve ads form the same domain, etc.
