This is victim blaming.

Only to some degree. The guy is a software engineer and should have known better. I’d agree if it was Jenny from accounting. You could just as well point out “victim blaming” when I called someone a moron for jumping from a three storey building and breaking his legs, because it was neither his intention nor was he aware that it could break his legs. For a software engineer to employ cloud based “smart” devices and then wonder if it backfires is borderline moronic.
