  • Off topic, but the rules of math are not set in stone. We didn't start with ZFC, some people reject the C entirely, then there is intuitionistic logic which I used to laugh at until I learned about proof assistants and type theory. And then there are people who claim we should treat the natural numbers as a finite set, because things we can't compute don't matter anyways.

    On topic: Parsing notation is not a math problem and if your notation is ambiguous or unclear to your audience try to fix it.

  • At least the private contact discovery is not very private:

    The client calculates the truncated SHA256 hash of each phone number in the device’s address book.
    The client transmits those truncated hashes to the service.

    Phone numbers are so not-sparse that there even was a game to text your "number neighbor". I can probably build a pretty effective rainbow table for this with my current hardware.

  • WhatsApp started is an XMPP client, but they use lots of proprietary extensions (doesn't matter since they don't federate). You can build very robust and scalable messengers with it if you want to.

    The open source implementations are developed by like 1-2 guys in their spare time and they're not far behind (and sometimes even ahead) other federated messengers which received tens of millions in venture capital funding.

  • If you need to convince your friends to use some app it might as well be XMPP compatible instead of another walled garden. If you can get your friends on board, you win, even if nobody else uses it.
