@d_rift I think the grocery store example basically fits if you have the primitives - video data goes to remote storage on the web without access control.
How likely is it for someone to get access? Pretty likely, and if you don't know that you have enough context to ask and understand the answer
How bad is it if they do? Probably fine for most people - it's a little worse than just being seen in the grocery store, but not much.
That's different from your reply though - my opinion is the average person shouldn't really have a finer-grained knowledge than "me (and anyone with my credentials) and the provider (and anyone with their credentials) and the world (delete as applicable)".
And I care more about the average person than I do about targeted individuals with powerful adversaries, because that's when you have a duty to learn more and also have to think about risk appetite - nobody is particularly secure when there's a laser mic on their window and people with no legal repercussions for getting physical. There's a point of diminishing returns which is totally personal. If you are literally or figuratively in a bunker, it's probably more pragmatic to do a Snowden and start talking to your enemies' enemies.
