For clarity: This relates explicitly to UA not GA4. That doesn’t however mean that the current version is deemed GDPR compliant; that is likely something that a future investigation will decide.
Google claims that GA4 should be compliant, but at the same time they have also for years until a few days ago been providing a version of GA that wasn’t.
In fairness, as a service, they were basically just handed a golden ticket.
True, and they are making lemonade for sure.
But again, my issue is with sleezy advertisement for a ‘profitable open source’ product.
