@dsoft@techhub.social @watomatic@fosstodon.org Speaking from our own history: we had to change our name from DAVdroid to DAVx5: You've almost zero chance. The first thing you would need is a lawyer and send them the official response and your sights. But at the end you will always be the weaker party (=less money). They will argue that you're free riding, using Whatsapp to make your own "business" ("your app wouldn't exist if there was no Whatsapp"). IMO u can only survive by removing any WA reference from text and images..
