Apple definitely exploits their dominance to kill innovative companies. I was a Spotify premium user for a long time. Then I got an Apple Watch to run with, but needed to download music to listen offline. Not surprisingly, I discovered that Apple doesn't implement the technology Spotify needs to download/play music offline on the Watch. But of course Apple Music works offline on the Watch. So for now I've cancelled Spotify and moved to Apple Music until such time I can use Spotify offline on the watch.
