The law is what the courts say it is. Many German newspapers have gone with the "we're a paid service but we'll offer it for free if you consent to tracking" approach, which has so far held in the lower courts, but hasn't (last time I checked) been decided in the equivalent of the Supreme Court, neither in Germany nor EU-wide. Facebook would be a good test case for this. That said, if you run facebook in a separate browser profile or container, or even have a good tracker-blocking list and extension running and don't let FB set third-party cookies, then it's a lot harder for them to track you off the platform. You then just need to decide how much of your life you put on FB itself.
