Regardless of the license (apart perhaps from public domain) it is legally still your copyright, since you produced the content. Pretty sure in EU they cannot prevent you from deleting your content.

You can when it comes to copyright. That’s EU-law and anything else would be such a horrible idea that no country would ever set up a law saying otherwise.
If you could simply revoke copyright licenses you would completely kill any practicality of selling your copyrighted works and it would fully undermine any purpose it served in the first place.
