Once again, under GDPR, it is entirely legal to issue fines without a warning. Therefore, in any case where it does not say that there was a warning, one can reasonably assume that no warning occurred - especially given that in some cases (according to you, most cases) they did say something about a warning. The absence of the mention of a warning in this context implies that there wasn’t one.
The point is, and no one has been able to refute this, that warnings are not required under GDPR. Even if they have issued warnings in most cases thus far, it is still early days. As these actions under GDPR become more common, there is no guarantee that even those countries that have been issuing warnings first will continue to do so. The enforcement of regulations that have the potential to generate massive revenue streams for government entities tends to become increasingly aggressive and creative as time goes on.
I don’t understand why anyone, even those in favor of GDPR, would attempt to refute the black and white text of the law. No warnings are required under GDPR, and thus the potential exists for fines to be issued without warning. There is no argument or opinion to be interjected here. This is a binary fact. Are warnings required? No, warnings are not required. It’s that simple.
