Well yeah, but that's in part a problem with always-on doorbell cameras. On paper they're illegal in many countries (privacy laws, you can't just put up a camera and record anyone out in public), in practice the police asks people to put their doorbell cameras in a registry so they can request footage if needs be.
Anyway, I get wanting to see who's ringing your doorbell in e.g. apartment buildings, and that extending to a house, especially if you have a bigger one. But is there a reason those cameras need to be on all the time?
At least in the USA it’s legal to record public spaces. So recording the street and things that can be seen from it is legal, but pointing a camera over your neighbors fence is not.
And a lot of people don't share that opinion, so this isn't the law in a lot of countries. When you wanted to suggest that it is a problem, that US companies try to extend the law of there home country to other parts of the world, then I endorse that.
