This is not true. Even if you are perfectly compliant, you need a complaint-response mechanism and lawyers in the EU ready to react to invalid accusations.
Given GDPR took a complain-investigate model, one also needs to be ready for power-tripping regulators. (Recall the Romanian data protector using GDPR to seize sources from a newspaper investigating corruption allegations [1].). Protecting against that requires, if not active lobbying, keeping lobbying connections warm. That costs money.
Ironically (and predictably), I’m seen more data being funnelled to Google than before. They have the scale to deal with this crap in each of the EU’s (currently) twenty-right member states.
