Man, this is just a message app. It's trivial. The law must mandate it to work.

The reason Whatsapp won out over competing services in the first place (over here at least) was that they managed to be both free and relatively spam free. All free alternatives quickly got subsumed by spam (even non-free SMS has a spam problem nowadays).
I don't know if you know this, but the EU cannot force a company to obey EU laws outside of the EU.
'Intel v Commission (C-413/14 P, 2017)' is another case where EU Antitrust explicitly punished global conduct outside of the EU.
Right now, with exception of antitrust, EU laws only incidentally affect global conduct, e.g. once a business is compliant with GDPR, it's often too costly to restrict compliance just to the EU. Nothing stops that from changing. EU absolutely can make a law that obliges e.g. chat app providers to either apply EU privacy standards globally or face bans/fines/seizure of their EU operations.
