It seems that a main differentiating feature is also the fact that all calls are end-to-end encrypted.

Perhaps as a video-calling alternative to Whatsapp? (given that neither of them are open source)

However like big brother, Google stores everything and runs machine learning algos on top. That's a big no no for privacy.

If they do indeed use end-to-end encryption, there should be nothing to store/learn for Google. Though without it being open source, there's no way to be sure. Unless maybe they start collaborating with Moxie, as Whatsapp did.
