I have always found it very telling how people who support free speech change their tune when they stand to lose their platform and audience because other people on those platforms do not wish to associate themselves with them. Would you prefer if artists like Neil Young and Joni Mitchell were forced to keep their content on Spotify even though they don’t agree with their association with Joe Rogan at the present time? - or if not, then what exactly is the problem?
Freedom of speech and freedom of association are two sides of the same street. If Joe Rogan is free to say whatever foolish nonsense he wants, as I believe he generally is if he’s not actively harming anyone, then Neil Young and Joni Mitchell (and others) are free to pull their content from the same platform to protest the platform bankrolling him. You should have freedom of speech, but there is no such thing as freedom of a platform for it - if people don’t want to hear it or be associated with it, they don’t have to, and they can withdraw their support (financial, content, etc.) of such platforms.
Also - it’s Rockin’ In The Free World, and the song is a biting and cynical satire. I’m not sure how you’re drawing a line between these two things unless you haven’t heard the lyrics before.
