Business users vs. platforms – a (not entirely) new battle frontier

The recent complaint of Spotify against Apple is yet another case concerning the contractual relationship between online platforms and their business users that appear to arise quite often these days.

The recent standoff between advertisement application developer Unlockd and Google, concerning the removal of Unlockd from the Google Play Store and AdMob marketplace, may turn out to be one of the most important competition law cases of the year. This case, which will likely require a competition law review of Google’s terms and conditions for these platforms, provides the opportunity […]
