Nonsense. Most of them do. Deezer even offered a bigger music archive in the beginning. Tidal started as sub only but added a US only free tier, instead it pays its artist much better.
In either case, I do think some of the points the other comment made are prescient. Spotify Connect is definitely a killer feature and I think Spotify Wrapped is one of those cultural phenomenon that you can't reliably predict the impact of. Network effects definitely seem to be quite powerful.
