Chrome safe browsing feature shows a warning if you browse to a URL which Google have flagged as hosting known malware. If you described this as "Google blocks your device from connecting to servers that don't have their approval" would the listener get an accurate understanding of what was and was not happening?
If Chrome scanned downloaded files for viruses and you described that to someone as "scans your computer for viruses" do you think the listener would come away with an accurate understanding of what was happening and accurate understanding of what they were and were not being protected from?
If BestBuy GeekSquad offered a service to "check your device for problems" and all they did was open your photo collection, would you walk away arguing that it proves the screen and mouse and CPU and disk must function and nobody could expect them to do any more than that, service provided, full marks, that's "the device" checked? Or would you hope that "checking the device for problems" might involve at least exercising all the major features like speakers, wifi, bluetooth, at least once, and preferably with stress and thermal tests?
When the TSA ask you to switch your device on to demonstrate that it's not a bomb, are you on the side of "if the screen lights up, the device is thoroughly and effectively tested and cannot contain anything else" or on the side of "an attacker could make up many ways to make the screen glow while hollowing out the insides, this does not really demonstrate that 'the device' is safe"?
