This, I think, is the core issue. The Privacy Policy is seen as the same type of thing as the Terms of Service. Of course, this begs the question of why does there need to be two different documents.
GDPR has pretty explicitly tried to reverse this. The Terms of Service can be as legal-y as you want, but there must be a plain-language Privacy Policy for the data subject. We'll see how much that happens in practice... the regulators probably have much bigger fish to fry than unclear PP documents, but a fine for a separate issue could include "no one could understand this, so it doesn't count" as a way to side-step technical loopholes.
