They do. "skip" does things other than skip the song.
They also had a dedicated dislike button and removed it years ago. Apparently what they are doing now works better.

Building a naive recommendation engine and giving it more good data – paid for, and also not factoring in the difference in time spent acquiring it – will obviously yield better results in a direct comparison. Striking a comparison to what Spotify is doing is pretty naive.
When you remove a song from one of the auto-generated playlists (Discover Weekly / Release Radar) the app requires you to specify a reason, “I don’t like this song/artist”. Isn’t this effectively a dislike button? Or is this input not used in playlist generation?
Do you know if the algorithm takes that into account?
I also became suspect of the behavior of the skip button, I sometimes skip songs of artists I really like and could observe that I did not get them recommended anymore until I explictly played a song of them. Of course this could be just random luck but it made me careful to skip my favorite songs and instead I open the playlist and select the next song.
