Personally I would prefer more neutral language. Something like "As a consequence of GDPR, companies have started changing their behavior from X to Y." If you want to give the readers context you could optionally add "Y is already law in the UK, but UK prosecutors have for the most part chosen not to enforce it."
So lots of firms, including some I've worked with, have huge mailing lists with addresses from multiple sources and are _pretty sure_ they got consent in all of those cases, but have no way of showing that if asked.
