This is the norm in Europe. Filming a crowd is fine, making a picture of the Eiffel tower with people around it is fine, filming a specific person and publishing it without their consent generally isn't. "Generally" because obviously it gets more interesting in the specifics of when it is ok, but those are exceptions similar to how copyright has exceptions.
“THE TOWER ILLUMINATED
Controlled use
The various illuminations of the Eiffel Tower (golden illumination, twinkling, beacon and events lighting) are protected.
The use of the image of the Eiffel Tower at night is therefore subject to prior authorisation by the SETE. This use is subject to payment of rights, the amount of which is determined by the intended use, the media plan, etc.”
Not at all actually. There is a constant stream of compromising material posted online in Europe. It's a huge problem actually, because it's notoriously hard to get such stuff taken down, as the authorities simply do not care.
