Differences between countries are funny. For instance, in France Rings don't fly because you're filming a public place, and by default people have an expectation of privacy and the right not to be filmed. If you want to film a public place (like put a camera that covers the street), there's a specific process to follow that includes getting a permission from the privacy authority, putting up warnings, and having processes (who has access to the videos, when, why, etc.).
And another point. You might not think video outside your home matters, but it could be invaluable to burglars who want to know when you're not home. I could imagine it being used to deanonymize location data as well because it would provide known locations and timestamps to filter data against.
They can also just park on the street and watch you…
So you could make an argument that woth their terrible security track record, numerous leaks etc Ring is more of a help to potential burglars than it is useful as a security device.
