A user is typically a natural person. A username identifies that person. Any information that is directly or indirectly linked to that username is thus personal data of that person. The GDPR explicitly gives “online identifier” as an example of an identifier. I did link to the official repository, which hosts translation in all European languages. Each translation can be reached with 1 click. It cannot be a language issue. I do not understand what the problem could be.
The personal data in the OP (consent options) are linked to a person via a cookie stored in their browser. I do not understand how one could make sense of the case without understanding what personal data is.
There also appears to be some confusion between GDPR and copyright. I do not know where these strange ideas come from.
I still don’t get where all this disinformation comes from. What do you mean by “the GDPR website”? Are you under the impression that the linked website is somehow official? Even so, the information seems solid and shouldn’t give you these ideas.
