(This does not mean that everybody conforms to the law. But people that don't would be at least liable for damages.)
Edit, to clarify: Of course you can film in public. But you're required to cut out people who didn't give explicit consent before showing the material in public or handing it over to third parties.
No it isn’t (there are similar laws in at least France and Italy, and a much broader one in the UK).
All of this delightful nuance goes to my previous point; there’s plenty to debate and discuss here and the whole idea of an absolute right to privacy in public is comical.
No it doesn’t. That consent is gated around violating their legitimate purpose (see the other words in that second paragraph). So in general just posting stuff/uploading to TikTok/facebook/etc does not require consent and you don’t have a right to have it taken down without specific cause.
It's my right to demand that.
