Yeah I could see it being left like this for an hour or so while someone finds out what the actual security configurations are supposed to be, during which time it wouldn't have any data in it. But to leave it like this for any period of time is ridiculous and to release it like this is criminal.

It's not great, but it's an acceptable kludge if you're the one holding everyone back and you can't figure out the problem immediately. Set it to public, let the devs get to work and research the problem until you find a real solution.

The test environment data should be generic so if someone were to discover the bucket they'll get some pictures of cats and a bunch of people who live at 12345 anywhere street.
