This may just be a semantic argument. Media production can consider it piracy, but that’s irrelevant as it had no legal standing. Without a law prohibiting something, it’s legal. And the fact that they sued and lost means it was never illegal and the media companies can declare it “piracy” or “treason against Columbia Pictures” or whatever they want until they’re blue in the face but no one cares.
Which is weird because neither of those things are illegal. You can absolutely tape the radio. You just can’t distribute it. Just like you can copy your own media for your own use as much as you want.
