I don’t disagree with your main point, but I’m not sure it’s really even “stealing”, as that means to take without permission. In this case, the storage permissions were configured so that the files were publicly available to everyone, so everyone had permission to access them.
Semantics though. It’s still unethical to access that data, even if it’s not technically stealing.
Many years ago, when I was repairing computers for a living, spyware like this was highly frowned upon.
I haven’t touched Windows in a few years, but I’m still somewhat saddened to see how normalized this has become. Why did society stop valuing privacy?
