Part of his deal was absolutely no meddling. Now whether that was handshake only or in the fine print I don't know. Rogan didn't need Spotify, but was growing upset at other social media's lack of definable policies.
This wasn't about money, it just took a lot of money. This was about being left alone to have on the guests that interested him. In spite of headline impressions, Rogan loves to learn about everything. His guest list is mind blowing. Do we always learn from the correct places, of course not. And even when humble about our limitations do people sometimes double down on stances when feeling the pressure being applied to think a certain way, unfortunately. But bottom line he's a comedian. Which means his nature is to laugh at the absurdity of the world, then to flip it on his own ego, and then spin it back around for hopefully some good. At least that is what I've gathered over the years.
