Hello folks, first things first, I have to advertise that this post has nothing to do with GrapheneOS. Sorry if it disturbs and I would perfectly understand if the mods want to suppress/close it.
So I have set up my own self-hosted server with a bunch of apps, including xmpp/ejabberd.
I use xmpp to communicate with my family members, since I couldn't get any other third person to use it. I use the good old sms with other people, which is not very confidential (although probably not listened to by the Big Tech). So I was wondering what would be the cons in terms of privacy if I add up a Whatsapp transport to my xmpp server. I suppose Whatsapp would get the metadata of the messages I send/receive (contact, date and time) ...
Does anyone here have more light about this ?
