That's because Miley was under age and a Disney princess. At least Britney waited till she was like 19 to dance on a pole, and even then it wasn't like a stripper the way Miley did at 16.

I think the reason why no one calls GaGa a whore is because she is not sexy and does not ooze sex the way Britney and Christina did. GaGa looks like she smells like an old can of tuna.
