There's a lot of detail, but the most important part is this: "...inactivity should not therefore constitute consent."
While I'm not sure there's an EU-wide ruling, the Greek DPA has specifically called out the "Consent" option being more visually prominent than the "Not Consent" option. They also mention the anti-pattern of bugging for consent daily but not bugging for un-consent afterwards, but that probably runs more afoul of "consent must be as easy to withdraw as to give" rather than "freely given."
