Apparently Europe finally got Whatsapp to enable 3rd party chats making it easier to switch to more privacy friendly alternatives article However the only other app that currently works with it is “BirdyChat”??
Have anybody found any news about when serious alternatives will be integrated?


WhatsApp was originally built on, and still is, a forked version of XMPP. It is nothing like the matrix protocol.
It’s not, but they made a WhatsApp API for the DMA. There’s a Matrix bridge to WhatsApp.
