In a legal context there's also the concept of a "reasonable expectation of privacy". The computer abuse and fraud act defines hacking as accessing data or systems you are not authorized to access.
A better analogy is putting your journal in a public library and getting mad when somone reads it.
I'm not saying what these ass holes did was right, I'm saying that the company weakened their legal position by not protecting the data.

Yeah the internet by design is a public space, and we must be responsible and treat it as such when handling sensative data.
Again, it was very wrong for people to take that data and especially to post like that.
The company also has to do their part and produce at least some kind of barrier to the data.
Even using UUIDs and making sure the data wasn't query-able would have been something.
