Whats "technically correct"? You think making a money sending feature using a currency that has random 1000% swings from fraudsters is "technically correct"? It's fucking useless garbage is what it is. Good thing their users didn't buy into the fraud seeing how this scam has no volume (ironically enabling this scam).
Rage against it all you want, people are judged by the company they keep. Ideally not in court rooms, but in everyday life? Abso-fucking-lutely. You don't have to like it but that's how life works.
Moxie was a technical advisor for mobilecoin, helping people send money privately sounds like a noble pursuit to me. At least it has a real world use case + legitimate real world userbase/implementation. Most crypto companies don't have that.
I don't think a messenger should provide a way to transfer money. It is one reason I hate Facebook Messenger. I liked Signal more before then because of its focus on messaging.
