I see no mention here of using a pre-existing standard chat protocol like XMPP or Matrix, it looks like they rolled their own. Therefore this is not interoperable and is yet another proprietary walled garden. No GNU/Linux client either. Next.

That's the way the game is played in the IM space. Sucks, but the only way out of that is to build an open source product.
