I'm curious, what about this do you find evil?
"If you deactivate your account, we'll kill this kitten."
Same essential principle.
If you want a detailed ethical analysis, it would have something to do with saying that your friends will miss you, as though they're asking you to stay, when they said no such thing.
Actively threatening a life.
"Your friends will no longer be able to keep in touch with you."
Suggesting there might be passive harm caused directly by a user's action.
Yeah, those two are ethically correlated.
