@purism Great post, but the Spotify criticism is weak and reasonably explained in the articled you linked to. Linking that particular criticism with "exploiting people" is disingenuous. There is potential, but no evidence of harm.
The linked criticism about mood targeting criticism is based on people selecting a mood themed playlist, not individual profiling of listening habits.
There is a multitude of actual harm to use for your argument without resorting to FUD. Please do better.
