There might be a legal distinction between "breaking and entering", "burglary", "trespassing" etc, and in a legal sense, whether the front door was open might have some impact on whether the act was illegal or not and what the consequences are, but in colloquial usage, you've still been robbed.
I think this is a more apt analogy to what az16 did here
But IMHO it’s hard to feel to bad for someone (az16 in this case) who handles their arguably most valuable goods in such a manner and gets robbed.
It's not an invitation to take it, it's just really stupid.
The particular problem here is we think of the crime on the web in a civil/criminal manner... "People should just follow the law or be punished for a crime". This is not the internet. Regardless of what you think about the internet, it is an international war zone. If you leave the hatch of a tank open and a drone blows it up, that was you being stupid. If you leave an ammunition truck unguarded and the enemy takes it, again, that is you being stupid.
History will look back and say WWIII started on the web, but as of now it seems a huge number of people are in denial about it.
Do you cultivate vines with fruit, or do you cultivate brambles and eat thorns?
Remember white hats don't need to exist. Black hats will exist by the very nature they are parasitic and thrive where exploits exist. We can either have a community that warns you that "Hey, the stuff on your porch is going to get stolen" or we can have a community that calls their buddy when they see some stuff fresh for the taking.
A huge portion these discussions under this article are people arguing the minutia of a puddle in the lawn while a 10 meter high tsunami is rushing their way.
If there were a convention of leaving stuff on your porch to donate it, and a general assumption that when people left stuff on their porch it was up for grabs, somebody started storing their groceries there, and they were taken… they would just be stupid and not sympathetic.
If somebody just moved to a neighborhood where this was tradition and didn’t know about it, they would rightly be a little bit annoyed when the groceries they stored on their porch were taken, but really they only have themselves to blame for not understanding the local conventions.
If somebody opens up a storage company and then just put all the customers’ stuff on one of these porches, they are just dangerously, unethically incompetent. Even if there isn’t a convention of taking stuff from porches, actually. Because there are also armed gangs (nation-states) that go check out people’s porches for secrets.
Only the burglary, trespassing, or B&E parts. Theft is still theft even if you leave your doors unlocked and/or open.
If someone doesn't know they've been a victim of larceny until later, it wasn't a robbery.
In this case, a person was yelling through the front door "Your door is wide open!" and no-one was listening.
For a 42B AUM company, at a time where running an IT operation means "use CrowdStrike so that you pass audits", leaving the front door open all night should get you fired, regardless of whether you blame hackers or not.
If I wanted to try to use such a weak analogy, the analogy to hacked is not robbed. You were only robbed if content was removed and exclusively held by someone else, which in the security world we call a ransom.
You can see how quickly this breaks down.
