Indeed, it's a powerful weapon against anyone who depends on general public popularity for their power (for example many/most elected officials). This is in fact one of the things that is highly investigated for getting TS/SCI US government clearance. They don't want to employ anyone who possibly has dirt against them in the open.

For a public official I can see why it would give them some leverage, but Jeff Bezos/Elon Musk/any rich dude doesn't really have to care. Did the "fappening" damage anyone's career?
