Imagine a disturbing box on a startpage which asks you for consent to some data processing, e.g. to show you the best matching advertisements. That box has a big ok button at the center and a small cross to exit at the top. That's a situation where most people will press ok and give clear affirmative consent.

Since most people press ok, it doesn't matter to also offer the service to those who cancel. Actually those people still leave a signal and you can show special ads to anybody who isn't part of the ok-clicker database.

I don't see how this would violate the GDPR:

- unambigous and clear affirmative action. People press ok and not the closing cross.

- no pre-ticket opt-in box

- distinct consent to advertisement processing

- separation from other terms

- not a precondition of signing up

- remaining right to withdraw consent

- ability to also tell people about their right to withdraw in that box

- possible to offer an easy way to withdraw

Actually withdrawal has to be as easy as consent. The law states:

>It shall be as easy to withdraw as to give consent.

That's the point where everybody is violating the law because the opt-out button is not constantly shown like the ok-button for opt-in.
