The primary issue with Rogan is him having a platform and being paid crazy amounts to spread, accidentally or naively, misinformation to millions of people, which isn't anything the same as Harris/Lost Prophets and so on being on Spotify. The racism thing draws a parallel for sure, but the financial contract Rogan has with Spotify raises the stakes a lot.
So far Rogan/Spotify have only removed a number of his podcasts. Presumably those are podcasts with questionable content. The equivalent hypocritical action from Spotify would be if they left online songs about paedophilia from Harris/Lost Prophets.
