The RGPD wall of Techcrunch is a real put-off (Choice partners that cannot be deactivated, IAB partners that must be unsubscribed from the third party website (which of course does not work), seriously?). No reason to accept this cancer, I will read about this subject elsewhere.
I stopped clicking on techcrunch links a long time ago for same reason. I am pretty sure that wall is not GDPR compliant, because the way to opt-out is not simple and straightforward.
And of course, GDPR is all about opt-in, not opt-out. The only statement that applies to opting out is 'withdrawing consent shall be as easy as granting it', which of course applies only after you've intentionally, explicitly granted opt-in consent.
