Apple and Google's duopoly is natural, no question about it. That doesn't mean we should ignore how they use it.

Google is rightfully scolded for requiring that users sign away their information and following their every move (often using dark patterns).

Apple should be put on hot coals too for how they are abusing their position. Spotify is an excellent illustration because Apple is both the platform and a competitor. I don't understand why an Apple consumer would support their anticompetitive stance.
