I have decidedly mixed feelings about this. In general, I don't think people should just be allowed to record and post other people's private moments. I think we don't want to live a life where we are at risk of every single thing that we've ever done being posted as video.
On the other hand, I travel a lot, and I take videos frequently to protect myself. Almost invariably, what I'm talking about here is walking around a rental car when I pick it up and drop it off. But there are other scenarios, like documenting that I was at a gate on time if they're claiming I was late and denying me boarding.
Of course, there are the ones that are contemplated by this article, like a dispute with another passenger or someone about what happened or what's happening, since the consequences of that stuff can be so severe.
I think a lot of European countries have laws around this that usually have exceptions for scenarios like that. For example, I was once recording the condition of a drop-off rental car in Italy. The rental car employee started screaming at me, claiming that, since he had been in the frame at some point or another, what I was doing was illegal. Meanwhile, he was refusing to give me a written receipt or some other proof that I had actually returned the car. If you know anything about rental cars in Italy, you want that, so I just took the video to confirm that I had, in fact, given them the keys and the car.
After it blew up and some research was done, it became clear that, while Italian law does have very strict restrictions on publishing recordings of people, recording your own customer service interactions for purposes of protecting yourself is clearly allowed.
I think a fairer policy here would be sharing, publishing, or distributing any recordings is very strictly prohibited, but merely possessing them can be permitted if the recorder can make a bona fide assertion that it was done for purposes of recording or protecting themselves and their rights as a customer.
