Unfortunately all my sources are in GERMAN. I am a German native speaker and observe the developments in Europe via youtube. I have formed my opinion through watching quite a few (German) videos on this subject.
I am pretty sure that my statements are essentially correct and the implications are factual, not exaggerated.
What I heard is that one will have to have WRITTEN permission of EVERY person in a photo. The fines are huge. This means a freelance journalist will not be able to post an incriminating picture. You will not be able to back up an alternative narrative with photos, reveal false flags, etc.
The burden of "security" measures for keeping data private will be so massive, that small businesses will not be able to do online marketing. Only large corporations will be able to do that, which is the goal.
And again the insidious part will be that you will have to give up your data voluntarily in order to get access to certain "privileges". The government is not spying on you anymore, you GIVE them permission.
A border guard might ask you for your data, to make sure you are not a "threat". If you comply, you might pass. If you don't...well...there might be a problem...

EDIT: Just think about it. When was the last legislation passed which was BENEFICIAL for us? It ALWAYS is to our disadvantage. It's all an illusion...
