I have never listen to a episode of JRE, but your link does not list a quote where he spreads misinformation himself. (unless you count a opinion “If you're like 21 years old, and you say to me, 'Should I get vaccinated?' I'll go, 'No.'”)

I suppose the issue is with some of his guests - but I think it is very legit for a podcast to have controversial guests in a free world.
