Germany bans Facebook from handling WhatsApp data over privacy concerns
The aspect I find most interesting and internationally relevant is that as these local rulings proliferate, they kinda make it visible to what degree companies finance their operations by selling user data.  The more the business model relies on this, the more likely companies are to get hit with a ruling like this — and it's not just the ruling that's interesting, but also what Facebook's reaction will be.  If they stop offering or reduce WhatsApp services in Germany (or India), that's a great indicator that the service isn't profitable without the sale (or other commercial exploitation, Facebook is an ad company after all) of large amounts of user data.
