Basically, GDPR forbids bartering of PII/tracking information with goods and services.
Why? Presumably because most users don't see the real cost of giving away their personal data (either they never recognize the cost, or see it too late).
To make sure this is held up, the GDPR uses some tools; one is that consent is freely given, the other is ban on tie-in sales: you cannot demand PII from users that isn't necessary for the service you provide.
If you provide news or stories as a service, you cannot demand location data from your users, because you can provide the service without that.
