> If the cookie banner satisfies the regulations
That's joke though. Most of them don't. And upon getting called out and/or fined, corporations right now just edge a bit further towards an actually compliant implementation - rinse and repeat. Currently we're in the state of "what if we made it really sloooow and convoluted to opt out?" - which is also not compliant because that makes not giving consent harder than giving consent.
At some point we're going to be there, but right now we're not.
The cookie banners as they are implemented right now are mostly wishful thinking by adtech: "Hopefully this will be enough?"
It's not. But nobody wants to be the first to stop widely tracking people and going back to good old contextual ads. They're going to wait until the EU turns the heat up to 100 and maybe even then wait for a competitor to blink first.
