Nah, companies don't want to implement it as it's bad for their business model so they feign ignorance.

I still remember being at an all hands at a former employer where the team presenting the revised cookie banners promoted as a benefit that it had opt in rates that would make an authoritarian dictator embarrassed to claim as uninfluenced

Considering the dozens of European governments that have been fined under the GDPR, I think it's safe to say that it's not just feigned ignorance.
