Why did you say "in the whole EU, I think?" It seemed to imply you grasped the context of the conversation already, but now the thread has taken what feels like a bizarre turn in a recursive direction.
> should someone take someone else’s photograph they should need their consent to post the photo publicly
> I don’t think posting a photo on a private social media profile / group chat would count as public
That all sounds pretty similar to what I know from EU countries. Of course, there are also exceptions like photographing groups of people etc., but I don't think that goes the spirit of the balderdash's concept.
