Unfortunately there are so much people that don't want to pay for the best alternative... :(
But well, I guess they will then have as only option to send me a message sending an SMS, which is the worst option of all.
I'm not going to use signal or telegram, because I don't trust them. Signal is popular, but it's based in the US, so that's a no-go... :(
Matrix is an excellent alternative, we should be trying to decentralize networks rather than put trust in a single entity who produce application/run server.
As for Wire being "swiss" i wouldn't be so sure about that. https://blog.privacytools.io/delisting-wire/.
Peer-to-peer protocols may be more metadata resistant, but they usually come at a certain cost, (least at the moment), eg. offline messaging, large rooms etc, present challenging problems. status.im, cwtch.im, getsession.org are providing interesting research, though still early days.
Matrix is even having a go at P2P as well: https://matrix.org/blog/2020/06/02/introducing-p-2-p-matrix
