> Though, as a public figure if your private life becomes embarrassing, or salacious you’re guaranteed to have news hounds on your trail.

This is like: if you engage in anti-social behaviour or plan some crime, you deserve to have hounds (law enforcement agencies, intelligence agencies) on your trail because of surveillance data that was gathered about you.

> Can’t take the heat, stay out of the kitchen.

This is like the political argument: "If you have nothing to hide, why are you opposed to the new surveillance law?"
