I still think Epic will allow download and ownership of FLAC files. They are quite open to ownership of content, I believe what they are trying to build is a stronger moat around their "app store". Longer term I think they will be looking to force Apple/Google to allow 3rd party app stores onto their platforms and in doing so need content.

This is a play to get content and direct relationships with producers, I don't think they will change the business model.
