I think the biggest thing with that is trump and Putin live public lives. They live lives scrutinized by media and the public. They bought into those lives, they chose them. Due to that, there are certain things that we push that they wouldn't necessarily be illegal if we did them to a normal, private citizen, but because your life is already public we turn a bit of a blind eye. And yes, this applies to celebrities, too.

I don't necessarily think the above is a good thing, I think everyone should be entitled to some privacy, having the same thing done to a normal person living a private life is a MUCH more clear violation of privacy.
