Spotify's business model is fine.
The reason artists complain and receive such little money doesn't have to do with Spotify itself. It pays 70% of all of its revenue out in royalties to the labels. The labels then pay out those royalties according to their contracts with those artists, as well as all the songwriters, producers and mixers that helped record that artists music. So the problem isn't with Spotify or even streaming. It's with the labels. So unless Apple is going to let royalties cut into more than 30% of its profits, there won't be much of a change in how much artists get.
The reason people are hating on Apple is because they're rumored to be attempting to get exclusives and get labels to no longer offer free music on YouTube or other platforms. Which is only going to drive up pirating rates.
