Without the force of law, this was never going to work.
Perhaps if the EU had used the presence of absence of the Do Not Track header as their method of determining cookie consent, it could have ended up being useful both from a privacy standpoint and to have saved us from the scourge of annoying as fuck cookie banners they ended up causing. Ah well.
Unfortunate, but understandable :(
I wish we could rely on good faith with something like this, but it seems the only way is to block as much tracking as possible by force.
