I think removing friction is so tempting for these tech companies because it has shown time and time again that that's what gas customers in. But there are really two types of friction, unwanted and wanted friction. Sometimes it's perfectly fine to remove unwanted friction like ad breaks when you're watching a movie. Then the line gets a lot more like, well, is music discovery an unwanted or wanted feature? In the moment, you think you just want to hear a song right now, but actually in the long term, meandering and listening to different records might be the right thing to do.
