Never in a morally neutral or positive way!

You "Bribe" your kid with extra time on the iPad. You don't "Bribe" them with wholesome things.

Not in a serious way, no (hence my 'mocking' commentary). It's always playing off the joke or idea of "bribe". But if someone said "I bribed a police officer" wouldn't take it as a joke.

Edit: And to be clear, I wouldn't describe either of those are "morally neutral or even positive situations."

But please, by all means tell me how "Foo Company bribed professional Bar" is used positively and frequently enough that the gp makes sense.
