You're saying is that when things are bad, it doesn't matter if someone makes them much worse. I think you're doing it for the sake of argument, and you'll find 1000 caveats why it only applies to what you want it to apply, because there's no possible way you'd go with in in real life. "Sir, you were bleeding anyway so it doesn't matter that we took your kidney".
It matters to the people who don't hand over their phone to a stranger. When someone hands of devices to a random stranger it's an exception and it goes against popular wisdom. When Meta does something hostile towards its users they do it for billions and the practice is normalized.
