Samsung has no music service but the built of open ecosystem is the partner with Google to deliver a good YouTube experience on their phones. I don't have to conform to Apple music if I don't want. I can trust other apps will work just as great. Apple undercuts other companies to keep users on their services, they would survive an open ecosystem, people would actually leave and you know that. If the Galaxy tab s7 worked with a Macbook, people would buy it for the iPad. Same for the galaxy watch because people have expressed love for the rounded design. Same for Samsung high end Monitors because they have superior quality but Apple makes Pro display limited with other devices
