It's funny to be how people complain about "the mob" when actions like boycotts and being deliberate about one's consumption are the only real power anyone not in government or on a board of investors has under capitalism.
It's all "if you don't like it, you don't have to buy it, but don't tell other people what they can't do!", right? But the minute people start getting together to say "hey, yeah, that's right, we DON'T like this, and so NONE of us are going to support it anymore" it's right to the handwringing about "bullying and censorship these days". It happens with other things, too, like the food industry... "don't eat meat if you don't like it!" becomes "what's with all these snowflake vegetarians these days??" So wait - we all have freedom to speak with our dollar, until we all start doing that, then suddenly people act like we owe these corporations out business...
Back on topic: I don't think Spotify's model is necessarily unfair, but I DO have a problem with it. See, it's not even that they SHOULD pay their artists more. It's that they COULD pay artists more, or heck, make their app better. Instead, they've built up a warchest to do things like buy off Rogan (who I dislike). If that's there business plan, and yet there are applications out there that use my subscription to give artists more while also offering a better app and higher quality stream (like Tidal), why is Spotify still owed my business?
At the end of the day, is it even about Rogan? I don't know. But the nonsense that goes on Joe Rogan's show and the obscene amount of money Spotify has invested in him has just given people pause to reconsider the other options on the table. And many have come to the conclusion that they don't need Spotify - there are better options out there, ones that offer a better quality product while doing more to support the artists.
