The public platform being the Internet. Nobody forced Rogan to move their content to a closed platform like Spotify. Before that they seemed to be able to discuss what they wanted with who they wanted. But instead of their freedom of content production, they picked the money. That's as simple as that. If they want to keep producing "freedom" content they just have to break the contract (and give back some of the money) or produce under another name on self owned platform (and build back the community).
