I think some of these might just be cleaning up for advertising? e.g. "Sarkon of Akkad" (Carl Benjamin) is an unpleasant liar who once declared "I wouldn't even rape you" to a politician online - not exactly perfect for advertiser's on Spotify Free?
Hm, yes "cleaned up" content for advertisers would fall exactly into that category. I think he should prefer platforms where advertisers cannot make editorial decisions. This should be clearly communicated to users, so that animosity from controversial topics is not directed at advertisers.
But in practice, directing animosity at advertisers and platforms is an effective way to remove content you don't like. It doesn't matter if the platform/advertisers says that they don't necessarily endorse the content--there's nothing stopping users from pressuring them regardless.
