Data protection agencies don't get to interpret the GDPR, courts do. The GDPR does not contain any clause that someone has to provide a service for free without any kind of tracking. That would basically eliminate Facebook and Google as valid business models. There was such a stipulation in discussion for the e-privacy directive but it was legally half-baked and IIRC it is out of discussion by now.
