Odd, I listen to NPR regularly and they definitely mentioned all three of those. But, not extensively because each ended up being a bit of a nothing burger.

I specifically recall talking about the lab leak when that got mentioned, since I thought the prospect was interesting. It eventually got dismissed and NPRs stance, iirc, was that there wasn’t enough evidence to really say any particular explanation was definitely true. They mostly moved on since everyone else moved on in that story.
