This is just me speculating here, but you guys have heard the saying that there is no such thing as bad publicity, right?
Spotify is going to use leftist rage to their benefit. It will create a massive amplification of the Streisand effect as people flock to Spotify and Joe Rogan to see what all the insanity is about, because people appreciate and recognize Joe Rogan for his world-famous show. The massive amount of attention will drive in MORE listeners, not less, even if some small percentage of lefties cancel out of rage.
They know that the listening audience represents a huge majority of their market. They wouldn’t cancel Joe unless there were some serious threats. Arkancide type threats.
"We could have got away with all this if people like Rogan weren't asking all those damn questions!"
