>Spotify owns distribution and has almost no competitors anymore
According to the statistics I have, Spotify has 34% market share while Apple Music has 21%, Amazon Music has 15% and others have 30%. That's hardly "no competitors".
Spotify doesn't own any distribution. The labels do, and they could just not renew their contract and move to a competitor's service at a whim, destroying the company (who wants a service where 1/3 of the artists are not available?).
They have the biggest share currently, but they're never safe.
