I read this as: "We will make sure that we will hide deep down in the terms of service you consent to us selling you data to the highest bidder"
The GDPR requires that you separate your requests for consent for ads from the consent for stuff which is actually necessary to be provided the service.
If customers don't consent to their data being used for ads, you can't use it for ads, but you also can't blackmail them by not providing the service then.
Also, you as a company are responsible to have the customer understand what they're signing.
If all of these would be done correctly, why would anyone ever sign the consent sheet for you processing their data to show them ads? All they get out of this, is their personal data at risk of being leaked.
