Stephen Fry is a public figure with a large following. He is mostly concerned with political matters, and he uses his influence to affect their outcomes. These days he is more accurately described as a political figure than an actor.

Whether he is seen as a good or bad person is immaterial. Public figures like Fry are not immune to attacks on the basis of their personal qualities. If someone's account is going to be accessed unlawfully, then Stephen Fry's is as good a target as any other. Fry is as much fair game as Britney Spears.
