Yeah honestly, it's a shame that every one of these services (whatsapp, signal, telegram, ...) dont operate on a protocol like smtp. Its completely unnecessary to recreate a chat protocol every time it gets implemented. Here we are though, and exactly the thing you are expecting is happening, several competitors that don't interact with each other so even if I want to delete WhatsApp, I still keep it to reach family and friends elsewhere.
