The article isn’t about the DJ feature at all, despite claiming to be. It is very clearly and openly about Spotify not catering to classical music in general. It starts by calling all people who listen to anything other than classical music “illiterate”!

It does not. The only reference to literacy is the following:
"The use of the word “song” for instrumental music — that is, music that is not sung and hence is not a song — is borderline illiterate."
That is entirely reasonable and correct.
