I can see why the industry didn't adopt the Do Not Track header, as it would basically kill all targeting revenue goodness that's been built up over the years.

I can see why the industry didn't adopt the Do Not Track header, as it would basically kill all targeting revenue goodness that's been built up over the years. Why not try and push for a unified IDFA instead, which has its benefits for targeting but also more control from a user perspective? I don't really see an industry adoption of these fingerprinting techniques. The linked page took 20 seconds and 100% CPU before getting a fingerprint ID, so running that at scale seems pretty useless?
