Streaming is moving from what Netflix was years ago, to a model where the distributor is the producer. The distribution part is comparatively easy, especially for a firm like Disney that already owns and runs content distribution outlets.
A diversified market for every distributor another platform isn't going to work. I recon people are not willing to take more than 3/5 subscriptions for watching their movies / series. And what if you want to watch that single movie, you need to go and buy that one, or do they offer a platform where you can rent / stream that one movie?
