The more common one is GDPR. Things like AI features come to Europe late, or don't come at all, because it's illegal to just record everyone all the time and transmit that information back to the mothership, which is what the feature does.
The EU accessibility mandates will be followed by apps, not by platforms. I don't care if Apple Music wants to keep being trash, Spotify, Deezer and Tidal will improve and lift everyone with it.
