What happened to David and Rob on the BP Podcast?

[Cody Z.]

Seems like out of no-where that BP has replaced David and Rob on the OG Podcast.

Dave Meyers thanks David for his contribution in about a sentence and doesn't even mention Rob.

No exit Podcast which tells me that it wasn't super amicable. Anyone know what the deal is?

I am super bummed to hear David Greene and Rob are no longer hosting. Besides always bringing a good sense of humor I am particularly floored by David Green's ability to explain complex concepts in simple to understand ways. I always feel smarter after listening to him. I have his books and will see where he lands next but I'm definitely bummed about a lack of an exit episode with him and Rob - really jarring as a regular listener.
