Not the GP, but yes, definitely. If a store or brand has collaborations with the wrong people etc., that's definitely a reason to not shop there. I don't find Joe Rogan terrible enough to cancel my spotify subscription, but if they started collaborating with say Alex Jones, I'd find another streaming service in a heartbeat.
Yes, which is one reason I dislike Rogan. However, Spotify and Jones aren't in direct business (making money off their business deal together). I'm fine with Spotify and Rogan doing business.
It's not that I go around worrying about what's said in every song and podcast on Spotify, it's rather whether I agree with Spotify's business practices or not. I wish Spotify told Rogan to stop having conspiracy theorists on his show (unless they are critically exposed), but I don't consider Alex Jones as being a part of Spotify's business model because he is a guest in one of their pods.
