Sure, someone might say, the way in which a television set shows a picture in response to a signal may vary. If the television is the wrong kind for that signal, then it just shows snowstorms, for instance. But that just means that the television misses information that exists, that is objectively there, carried by the signal. It is no kind of argument that the information is not really there, independently of the receiver, in the first place. If the transmitter is beaming the inaugural speech, a television showing a snowstorm is doing worse than one showing the speech.
